Insulation for pipes made of foamed polyethylene: choosing a method for insulating the water supply

Winter temperatures in the vast majority of Russian regions leave practically no chance for pipelines to remain intact without reliable thermal insulation. Insulation for pipes made of foamed polyethylene is an excellent way to protect utility lines from low temperatures, and when used on heating mains, prevent unnecessary heat loss.

Insulation for pipes made of foamed polyethylene

This material is inexpensive, easy to install, lightweight, produced in a wide variety of sizes, and has a number of other important advantages. It makes sense to get to know him better - he will definitely find a use in any household.

Areas of application of polyethylene foam insulation

Expert opinion: Afanasyev E.V.

Chief editor of the Stroyday.ru project. Engineer.

Foamed polyethylene for pipes is widely used for thermal insulation of sewer and water pipes laid underground, across the street or passing through insufficiently well-heated rooms. The presence of insulation guarantees that the transported coolant, water or sewage will not freeze in winter at subzero temperatures.

Due to the fact that all pipes produced for household utilities are made of materials with high thermal conductivity, such as steel, fiberglass and polymers, their freezing occurs quite quickly. Therefore, their insulation is simply necessary.

When a liquid in uninsulated pipes freezes and turns into a solid state of aggregation, it is not only capable of creating a plug in the channel that will slow down or completely stop the flow. Everything could be much worse - the expansion of ice has such a “power” potential that even thick metal walls cannot withstand it - they crack or burst.

When water freezes, it expands significantly in volume, which often leads to deformation and bursting of pipes.

Most accidents on central pipelines occur precisely because of insufficient thermal insulation. Therefore, taking into account other people’s mistakes, you should not save on this material, so as not to pay a much larger amount to restore damaged or even completely failed systems.

Even if the pipelines are buried below the freezing level of the soil, thermal insulation is still needed to prevent unnecessary heat losses

Highways laid in trenches dug in the ground are usually installed below the freezing level of the soil. However, hot water supply and heating pipelines carried out in this way also require effective thermal insulation, which will prevent heat loss from the transported coolant or hot water, which allows them to maintain their temperature as much as possible at all stages of delivery to the consumer. For the same purposes and in a similar way, the supply and return pipes in the boiler room are insulated if it is located in a separate unheated room, as well as in areas where they pass through other “cold” rooms.

Almost all materials used for thermal insulation also have sound-proofing qualities, so they are often used to suppress the noise produced by water passing through pipes in residential premises.

The installation of air conditioning systems cannot be done without installing thermal insulation.

Insulation is also required for pipes of air conditioning and cold water supply systems. In these cases, it is intended to prevent excessive formation of condensate, which may appear due to temperature changes between pipes and air, which will inevitably lead to premature wear of the system or destruction of connecting nodes. Thermal insulation material neutralizes this phenomenon, extending the life of trouble-free operation of not only the pipes themselves, but also the devices to which they are connected.

Main technical and operational characteristics

To understand the characteristics of foamed polyethylene, you should study the technical characteristics of this insulation; it is available in two types:

1. Unstitched.
2. Stitched.

The first type is a polymer, the molecules of which do not have additional connections in space, due to which the material has less elasticity, strength and density; when compressed, a characteristic crack is heard and the original shape is lost.

The second type is obtained by chemical or radiation methods, that is, between the PPE molecules under a specific external influence, not only linear, but also cross-links are formed, or in other words, “cross-linking”, that is, the material turns out dense, strong and elastic, and after its compression the original shape quickly is being restored. Therefore, in order for pipe insulation made of foamed polyethylene to be of high quality and effective, it is better to give preference to products belonging to the second group.

Main technical characteristics of cross-linked insulating material:

• thermal conductivity – from 0.037 to 0.04 W/m*K;
• density – 25/200 kg/m3;
• susceptibility to the effects of a humid environment – ​​0.9/1.1%;
• vapor permeability indicator – 1.8 mg/m*h*Pa;
• flammability group based on state standards – G1-G4;
• level of dimensional stability – high;
• noise absorption – 16 dB;
• operation at temperatures – from -60 to +90°С;
• service life – 80-100 years.

Basic requirements for thermal insulation materials for pipes

In order for the insulation to be effective and the money for its purchase not to be wasted, the thermal insulation material must meet certain requirements:

• Low thermal conductivity of insulation - the lower this indicator, the thinner the layer of material required. This factor becomes important in cases where it is necessary to insulate an already installed pipeline, or there is a need to save on this purchase.
• Hydrophobicity of the heat insulator . This quality should not be underestimated, since the insulation must not only protect the pipeline from freezing, but also from moisture, so that the metal is not subject to corrosive destruction. In addition, if the insulating material becomes moistened, its thermal insulation capabilities will begin to sharply decrease.
• Resistance to mechanical and atmospheric influences - these qualities are necessary both for thermal insulation of pipelines running along the street and for those buried in the ground.
• The heat resistance of the material is a property that is especially necessary for pipelines of heating and hot water supply systems. That is, the material should not “float” when heated around 100 degrees and should not become brittle in the cold.

Foamed polyethylene has all these qualities.

Advantages and disadvantages

If we compare foamed polyethylene for pipelines and thermal insulation made of expanded polystyrene and polyurethane foam (PPU), then foamed polyethylene has several advantages.

• Resistance to stretching, and the ability to restore the initial dimensions obtained as a result of deformation changes.
• Complete safety for humans and the environment. For this reason, this pipe insulation is used in industrial enterprises, at home, in medical institutions and in food production.
• This polyethylene is very easy to install. Parts made from hollow tubular elements make it possible to quickly install without the use of tools.
• The price of foamed polyethylene is lower than that of similar heat insulators for pipelines. For example, foam rubber, which has a characteristic black color, also demonstrates excellent characteristics, but its cost is significantly higher.

What is foamed polyethylene?

General concepts about polyethylene foam

Any foamed polyethylene, be it insulation for floors, walls or other surfaces of the house or heat insulator for pipes, is made using the same technology, however, the material can have different densities and thicknesses. Insulation for pipes, unlike those produced for flat surfaces, are manufactured in the form of cylinders of different diameters, which greatly facilitates their installation.

Polyethylene foam insulation for pipes is usually produced in the form of cylinders with a certain internal and external diameter. This is very convenient for quick installation

The production technology of this material consists of foaming the polyethylene melt with hydrocarbons, resulting in an elastic elastic fabric that has a bubble structure with closed cells. During the foaming process, under the influence of high temperatures, polyethylene increases in size almost 20 times, and then the finished mixture, after cooling, is passed through an extruder, where it is given a certain shape.

Polyethylene foam is produced in the form of sheets, rolled into rolls, shells (cylinders) and bundles. The material is divided into two types according to the manufacturing method - cross-linked and non-cross-linked.

• Non-crosslinked materials are designated as NPE and are obtained by foaming polyethylene with a mixture of propane-butane or approved freons. Under pressure in the extruder, the raw material is melted and mixed with a reagent (propane-butane mixture). At the exit from the extruder, the pressure decreases, the gas expands the polyethylene, resulting in gas-filled bubbles. At the exit from the apparatus, the finished material cools and hardens, maintaining the shape given to it by the extruder nozzles.

This type of material differs from cross-linked material in its lower density and strength, and less pronounced resistance to aggressive chemical influences. In appearance, it can be identified by larger cells, and when compressed, the material makes a cracking sound and no longer takes its original shape.

The illustration shows uncrosslinked polyethylene foam at the top and crosslinked polyethylene foam at the bottom.

• Cross-linked polyethylene foams (PE-X) are produced in two ways - radiation and chemical. Such materials are called cross-linked because under a certain external influence, cross-links are formed in polyethylene molecules, in addition to their characteristic linear chains - this is “cross-linking”.

Expert opinion: Afanasyev E.V.

Chief editor of the Stroyday.ru project. Engineer.

The chemical method of forming cross-linked material occurs under high pressure. Polyethylene with the addition of antioxidants and a reaction initiator undergoes melting under the influence of high temperatures. Then, in the molten state, the raw materials are “crosslinked”. The initiators of the formation of cross-links disintegrate at high temperatures, and radicals appear that take away one hydrogen atom from polyethylene. As a result, unsaturated carbon radicals are formed in their place, which combine to form a spatial structure.

The radiation method of cross-linking macromolecules is carried out under the influence of directed energy beams.

Cross-linked polyethylenes are more durable, elastic and have a high density. After applying and removing a deforming load, the compressed material quickly returns to its original state. This property of cross-linked polyethylene - the presence of a kind of “memory” of the original volume or linear size, is widely used in many areas of the economy.

Thermal insulation for pipes is produced in the form of cylinders, usually up to 2000 mm in length, or tubes sold in coils, and the diameter and wall thickness vary. For example, the thickness can be 6, 9, 13, 20 and 32 mm, and the internal diameter of cylinders intended for domestic needs can be from 6 to 200 mm; for industrial use, the figures can be larger.

In order for the thermal insulation to “work” properly, the internal diameter of the polyethylene cylinders must correspond to the external diameter of the insulated pipes. Therefore, manufacturers, knowing this, manufacture products with standard parameters, focusing on the produced range of water and sewer pipes. Insulation cylinders have an even cut along their entire length, often also equipped with an adhesive layer, which allows them to be installed on an already installed pipe without resorting to dismantling.

There is an even cut along the entire length of the insulating cylinder, the end edge of which is often equipped with a self-adhesive layer

To insulate pipelines that are directly exposed to ultraviolet rays, polyethylene foam tubes are produced that have a special polymer colored coating that provides the necessary protection to the heat insulator.

The external polymer coating of the insulating cylinders increases their resistance to negative external influences

Cylinders for pipe insulation can also have a foil coating, which prevents the material from overheating or overcooling.

It should be noted that if it is necessary to insulate complex pipeline structures or large-diameter pipes, roll material can also be used. They wrap water pipes of any diameter in one or several layers and fasten them with special tape.

Waterproof reinforced tape is perfect for performing thermal insulation work on pipelines, especially where fixing the insulation is difficult due to the complexity of the site configuration

In addition to heat insulators for pipes, sleeves are also produced for cable systems. This type of material has a fine-cell structure, so it can also serve as a waterproofing agent, which makes the material almost universal. It is especially important to use this type of insulation for overhead cable lines, which are influenced by various natural factors all year round - temperature changes, moisture, ultraviolet rays, ice, wind, etc.

Main technical and operational characteristics of foamed polyethylene insulation

The assortment of construction stores includes pipe insulation made from different materials - mineral wool, polystyrene foam, polyurethane foam and polyethylene foam. In terms of affordability and thermal insulation efficiency, polyethylene foam appears to be the leader.

The characteristics of foamed polyethylene from different manufacturers may vary somewhat, but their average indicators can be estimated:

• For example, a parameter such as density can be 20÷45 for non-crosslinked polyethylene foam, and 25÷200 kg/m³ for crosslinked polyethylene foam.
• The thermal conductivity coefficient is usually in the range from 0.037 to a maximum of 0.040 W/m×°K, that is, at the level of most modern high-quality insulation materials.
• The flammability group, according to GOST 30244-94, can be G2-G4 for uncrosslinked material, and G1-G4 for crosslinked material. If thermal insulation of open pipelines is being carried out, that is, those that will not be buried in the ground, then it is recommended to choose insulation with G1÷G2, which means low-flammability and self-extinguishing.
• The moisture absorption of foamed polyethylene is 0.2% for uncrosslinked polyethylene, and 0.9÷1.1% by volume for crosslinked polyethylene.
• The vapor permeability coefficient is the same for both types of insulation - 1.8 mg/m×h×Pa.
• The service life for NPE is 25 years, and for PPE – 80÷100 years.
• The ability to maintain shape: for NPE - medium or low, for PPE - pronouncedly high.
• Sound absorption is 16 dB.
• Dynamic modulus of elasticity – 0.78 MPa.
• The maximum tensile load is 0.31 MPa.
• The operating temperature range of the material is from -60 to +90 degrees. If the temperature exceeds the set threshold, the material may deform. That is, it cannot be used for steam heating systems.

The ignition temperature of high-quality polyethylene foam when directly exposed to fire is 300 degrees, and when burned, the material does not emit toxic substances that negatively affect human health, as it decomposes into carbon dioxide CO2 and water H2O.

Advantages and disadvantages of polyethylene foam insulation for pipes

Compared to other pipe insulation, polyethylene cylindrical bundles have a number of significant advantages, which include their following qualities:

• The thermal conductivity coefficient is not higher, and often even lower, than that of other heat insulators, which allows you to reliably protect the pipeline from the most severe frosts - just choose the right thickness and density of the insulation.
• Safety for humans and the environment. Polyethylene foam does not emit toxic substances harmful to the human body, even when exposed to high temperatures. This quality does not limit the use of this material in children's and medical institutions, on food industry production lines and in other similar areas.
• Chemical resistance. The material is inert to various building solutions, alkaline and acidic environments, so it can be safely used for thermal insulation of pipes laid in the ground or passing through the foundation.
• The moisture resistance of the insulation also allows it to be used when pipelines are buried.
• Resistance to biological influences. No microorganisms take root in polyethylene foam, which guarantees its safety from decomposition.
• The high level of sound absorption makes it possible to make the water supply system of a private home almost silent.
• The ability to recover after compression helps maintain the shape of the cylinder, as well as its thermal insulation qualities after such deforming influences.
• Low temperature resistance. The material does not lose its elasticity and resilience even at a temperature of -60 degrees.
• The affordable cost of the material allows it to be used for insulating the pipeline along its entire length. Polyethylene foam will cost almost half as much as insulation made from polystyrene foam, mineral wool or polyurethane foam.
• Convenient and simple installation of the material. To insulate pipes, you do not need special tools or assistants. You can do the work yourself without much effort.

If you plan to use this material for insulation, then you need to know not only about its positive qualities, but also about its disadvantages. Although there are not very many of them, they can be significant.

• Increased flammability. The material is strictly prohibited from being used in premises that are subject to particularly high fire safety requirements. Although high-quality polyethylene foam is a moderately flammable material, it is, however, unable to withstand fire for a long time and can ignite, and in addition, it supports combustion and, in a molten fluid form, can itself become a flame spreader.

Insulation tubes in a protective sheath. By the way, it is convenient for color marking of pipelines - you can immediately see where it is cold and where it is hot

• UV instability. If you plan to use polyethylene foam to insulate pipes running along the street, then you should choose products with a protective coating, otherwise under the influence of sunlight the material will begin to lose its qualities.
• Low mechanical strength. Foamed polyethylene can be easily damaged by sharp objects, and minor damage can cause such a rupture to spread further along the pipe. Therefore, if a small accidental damage occurs, it must be immediately sealed with special tape.

Production methods

Foamed polyethylene for pipes is made from PE, supplied to the enterprise in the form of granules. The raw materials are poured into a heating tank, after which special additives and dyes are added to it. When heated to 140ºC, a chemical reaction begins, accompanied by foaming of polyethylene and an increase in its volume. This substance is fed into an extruder, which gives the raw material a given configuration. After cooling, the insulation acquires density and elasticity. Then the blanks are cut into pieces of the required size and delivered to the packaging workshop.

The production of foamed polyethylene is carried out in the following ways:

1. Chemical. Under the influence of high temperature and catalysts, free radicals are released from raw materials. They bond with hydrogen atoms. In place of the selected particles, unsaturated carbon radicals appear, which, when combined, form a spatial lattice that gives the polymer volume, density and elasticity.
2. Radiation. The joining of molecules occurs during the bombardment of raw materials with directed energy beams of X-ray radiation. The operating principle of this technology is to knock out hydrogen atoms from molecules, which are replaced by carbon particles. Finished products do not emit radiation and are completely safe for human health and the environment.

Features of pipe insulation work

Polyethylene foam thermal insulation is quite simply installed on a pipeline of any complexity. As a rule, this process is carried out after the installation of the system pipes is completed, since the insulation will interfere with the joining. For this purpose, many manufacturers provide cuts on the insulating cylinders. However, solid insulation is also sold; it is easy to cut it along the entire length yourself using a regular stationery knife with a replaceable blade. A self-cut cylinder placed on a pipe will have to be fixed in one place, secured on top with pipe tape.

Installation of polyethylene foam thermal insulation on tubes usually does not cause any special problems

Before installing the heat insulator on the pipeline, you will need to carry out simple preparatory measures:

• The surface of the pipe must be cleaned of mortar and dirt, since the insulation must adhere tightly to it.
• When insulating metal pipes, they are first cleaned of rust.

When the preparatory work is completed, you can begin installing the thermal insulation. For gluing foamed polyethylene along the cut, as well as at the beginning and end of the sleeve to the pipe, the following brands of glue are used: “QUIK-BOND”, “88-NP”, “Akrol contact”, “Neoprene 2136”.

"Neoprene 2136" is produced in the form of a spray, so working with it is very careful and quick. The joints between two separate insulating sleeves are additionally secured with tape, which was mentioned above.

Insulating the junction of pipes on a tee

However, it should be noted that gluing thermal insulation with glue along its entire length is not done so often, usually only in cases where a pipeline running along the street is insulated.

The cut line can be taped along its entire length. Then it is necessary to carry out the same operation along the joint lines of adjacent sleeves.

Usually, simply connecting its edges and fixing it with tape is enough, the main thing is that the inner diameter of the sleeves is ideally matched to the size of the pipe. Well, if the end edge has a self-adhesive coating, then everything is generally simplified - the protective film is removed, and then the cut is securely glued along the entire length.

When using glue, the joint after joining the edges can be clamped with brackets in increments of approximately 200 mm until the glue dries (time indicated on the packaging). Then the staples are removed and the seam is taped. The next sleeve is mounted in the same way.

Types of products

Foamed polyethylene insulation has a wide range of applications due to the wide range of shapes and sizes of finished products.

Products are available in the following forms:

• rolls intended for packaging goods or thermal insulation of engineering structures;
• harnesses for insulating and sealing joints in communications;
• cylindrical tubes for insulating electrical cables;
• aluminum-coated layers to create a reflective and heat-retaining effect;
• mats for thermal insulation and shock absorption of objects and objects of various purposes and sizes.

Based on the type of manufacture, pipe thermal insulation is divided into the following categories:

1. Uncrosslinked PE. It is a porous polyethylene with low performance qualities. It is characterized by its heterogeneous structure, high thermal conductivity and fragility. Used for waterproofing and packaging products for various purposes.
2. Chemically cross-linked PE. Produced chemically and by extrusion. It has strength, density, elasticity and water resistance.
3. Physically cross-linked PE. It is made by affecting polyethylene at the atomic level. As a result, the finished product has a strong molecular structure. Insulation materials are characterized by maximum strength and resistance to external factors.

Manufacturers of heat insulators for pipes

In construction stores, insulation materials for pipes are mainly from domestic manufacturers, but it should be noted that Russian products have a very decent high quality and a more affordable price than imported products, so there is no particular point in chasing after some brands.

Thus, Termocom became the most popular producers of these materials. The first company produces insulation materials that contain waterproofing additives, while the second company pays more attention to ensuring the safety of pipes. Energoflex products differ from other heat insulators in that freon is used in their production, while other manufacturers produce polyethylene foam using a propane-butane mixture. Due to freon, the material acquires higher resistance to water vapor.

The cost of polyethylene foam insulation varies depending on its density, thickness and diameter, as well as on the method of its manufacture. It is clear that the range of prices, based on what has been said, is very large - from 10 to 200 rubles per linear meter.

In conclusion, it must be added that insulation for pipes made of foamed polyethylene will be an ideal solution if it is used under operating conditions acceptable to it, that is, not requiring increased fire safety measures. In the other cases listed above, the material will last for many years, without deformation or reduction in thermal insulation qualities.

Areas of use

Special casings are made for pipes, which are designed for any diameter.
The material is used to provide reliable thermal insulation coating for utility lines. Foamed polyethylene cases are suitable for insulating pipelines:

• heating;
• hot and cold water supply;
• sewerage;
• air conditioning systems;
• ventilation ducts;
• cooling units.

Sheet insulation based on polyethylene foam is used to insulate the walls of buildings from the outside and inside, basements, foundations, and attics. It is used for thermal protection of baths and saunas. Bundles of this material are used to seal interpanel seams and cracks in window and door openings.

Specifications

Thermal insulation for pipes made of foamed polyethylene has the following technical characteristics:

• thermal conductivity - 0.03-0.04 W/m*K;
• maximum temperature in the coolant - 180ºС;
• density - 25-40 kg/m³;
• hygroscopicity - up to 2%;
• vapor permeability - 0.001 mg/m*h*Pa;
• tensile strength - up to 0.3 MPa;
• elastic modulus - up to 0.7 MPa;
• sound absorption coefficient - 25-55%;
• operating temperature range – ±120ºС;
• service life - 20-80 years.

Manufacturing technology

Low-density polyethylene (LDPE) granules are poured into a hopper, where they melt and mix evenly. Next, the resulting mass is foamed with gas or special reagents. At this stage, pigments and modifying additives are introduced into the melt. Then the heated mass is pressed through an extruder to give the insulation the required shape.

Installation rules

During installation, the following rules must be observed:

• cut pipe insulation into blanks with a sharp knife on a hard surface, trying to make smooth edges (you can use a miter box);
• the joints between the cylinders are glued or fixed with plastic couplings;
• longitudinal longitudinal seams are fastened with aluminum tape or plastic clips;
• corners and cut-ins of larger diameter are wrapped with rolled polyethylene foam pipe insulation, overlapping with the main line, the joints are taped.

It is not recommended to glue longitudinal seams and cylinders with pipes. This will complicate the work during subsequent inspections, maintenance and repairs of the pipeline

Preparation

Before thermal insulation of the pipeline, a number of measures are carried out.

When preparing for installation, you need to take the following measures:

1. Turn off the hot water supply. You must wait until the line cools down to avoid burns.
2. Inspect the system for damage and corrosion. Draw up a work plan. Calculate the need for materials and make purchases.
3. Clean the metal from debris, dust and rust. If necessary, treat damaged areas with paint or a special anti-corrosion compound.

If there are faulty sections and components on the highway, they are repaired or replaced. The decision is made individually for each case.

The insulation on the pipe can be reinforced with wire. Compression of the material during installation is not allowed!

Dimensions

For insulation of pipes of various diameters, sheet and pipe versions of polyethylene foam are used. Sheets up to 5 cm thick are produced in rolls with a width of 60 to 120 cm. They are used to install thermal insulation on pipes with a diameter of over 16 cm. The length of the roll depends on the thickness of the layer and can be from 2 to 30 meters. The sheet may have a foil layer on one side of the material.

Foamed polyethylene is supplied in the form of tubes of different calibers for continuous installation of small-diameter pipelines. Tube sizes vary in length - from 1 to 10 meters. The thickness of the insulation walls can be: 6, 9, 12, 20, 25 and 32 mm. The internal diameter corresponds to the external caliber of the pipes, ranging from 6 to 160 mm.

Additionally, the polyethylene tube can have an outer polymer layer of 1–2 mm, which gives it mechanical resistance and protects it from ultraviolet radiation.

Where is polypropylene used?

Polymer synthetic material can replace expensive analogues, allowing to reduce labor and material costs. Therefore, it is effectively used in a variety of fields.

Food industry

In the manufacture of plastic bottles, dishes, lids, cling film, packaging containers (the polymer ensures low material consumption). Despite the fact that the products have minimal thickness, their shape remains durable.

Artificial threads

Strong, heat-resistant, elastic fibers are obtained from synthetic plastic (more products are obtained from 1 kg of the substance than from the same amount of another polymer). The disadvantage of special threads is their vulnerability to ultraviolet radiation. The introduction of modified additives makes it possible to increase its chemical properties. Ropes, ropes, twines are effectively used in the field of shipbuilding.

Machinery and instrument making

The high wear resistance of the material determines its widespread use in production:

• parts for fans, cooling systems, vacuum cleaners, refrigerators;
• fuse blocks;
• shock absorbers;
• filters;
• battery tanks;
• seals for body parts;
• bumpers;
• dashboard;
• floor mats, etc.

Pharmacology

Polypropylene is successfully used in medicine - it is used to make inhalers, syringes and other medical supplies that can be steam treated (sterilized):

• test tubes;
• sample and IV bottles;
• baths;
• Petri dishes;
• containers for tablets;
• elements of diagnostic devices.

Electronics

Thermoplastic material ensures high quality:

• insulating shells;
• coils;
• telephone sets;
• housings for televisions and radios;
• communication wires.

Package

Thermoplastic polymer films are a popular packaging material with high performance properties. Flexible, transparent, easily weldable and non-toxic, the films are sterilization and chemical resistant, making their value in the medical and food industries undeniable.

They are used as bags for packaging fruits, berries, vegetables, confectionery and bakery products, bulk products for transportation and storage. PP packaging is convenient, roomy, and lightweight.

An innovation in the packaging industry is specially oriented films that have increased transparency, rigidity, strength and moisture resistance. Glossy products successfully replace label paper.

Use of polypropylene in everyday life

• plastic furniture;
• carpets;
• dishes;
• oilcloth;
• toys;
• buckets, basins, flower pots;
• soap dishes;
• vegetable boxes;
• flasks;
• bags, garbage bags;
• disposable diapers and other household items.

Modern manufacturers choose PP as an alternative to other materials due to:

• environmental friendliness;
• cost;
• ease of disposal and recycling.

It is believed that the scientific potential of the thermoplastic synthetic substance has not been fully realized.
