Polyurethane - what is it? Polyurethane production, products from it

People who are interested in modernconstruction or production, often found such a material as polyurethane. What it is, and how it is used, you can learn in detail in this article. This substance is a very elastic polymer that is widely used in various areas of our life: construction, medicine, heavy, footwear or clothing industry. Naturally, this substance is synthetic. It has a lot of advantages, which you will now learn.

Material advantages

The presented material has quite a number of advantages:

· Resistance to wear, aging and external influences.

· High strength.

· It is possible to change the level of elasticity of the material.

· The ability to use substances with high loads.

· A wide temperature range in which polyurethane (which you already know) is able to be operated.

· It is applied in many spheres of human life.

· It produces sealants, clothing, insulation, shoes, pipes and other products that are used in everyday life.

· Durability.

· Affordable cost. This material, whatever characteristics it has, is inexpensive, so it can be purchased by any person with an average or even minimum wage.

· Practicality and versatility.

· No deformation.

· Does not leave marks on that surface with which interact.

Material properties and specifications

The most common material to dateday is polyurethane. You already know what it is, what virtues it has. Now we will deal with the technical characteristics of this substance.

So, the presented material can calmlywork in an aggressive environment, while its quality properties are virtually unchanged. In addition, the substance is well operated in a fairly wide range of temperatures: from -60 to +80 degrees. Sometimes it can be heated to 120.^aboutHowever, this process should not last long, otherwise the material will simply collapse.

The polymer is able to withstand heavy loads,less aging than other substances. It is resistant to wear, moisture, temperature changes, sunlight, salt, organic-based solvents. Polyurethane (what you already know) is considered to be a very durable material. At the same time, its elasticity can be programmed during production. This material may have different characteristics on which its scope of application depends. It should be noted that the polyurethane may consist of one or more components.

Features of the production of the material presented

It should be noted that the production of polyurethanecan not be called simple. It takes a lot of strength, labor and energy. The process itself takes place by mixing and heat treatment of several elements: polyol and isocyanate. In addition, polyetheramines are also added to this mixture. The whole process is performed on fairly expensive equipment.

It should be noted that the raw materials are producedin a few countries: Russia, Germany, USA and Italy. The presented material is manufactured and processed in several ways: by casting, pressing, extrusion.

What products are made of the presented material?

Polyurethane is a very common material.Many products are made of it. For example, in medicine it is used for the production of condoms, which are distinguished by durability, smoothness, low cost and environmental safety. Also from the presented substances are made tires for automobile wheels. They not only serve much longer than rubber, but also do not leave marks.

It should be remembered and such products from polyurethane,as o-rings, sleeves, cuffs. This substance is used as a heater. The presented material is used in the furniture industry for the manufacture of mattresses. If you buy polyurethane rollers, then you can be sure that they will last a long time.

This material also produces a variety of suction cups, guide elements, bandages, linings, pulleys, rail slats and other items.

Where is polyurethane used in liquid form?

I must say that this material canapplied in different forms: liquid, foam and solid. The first type of substance is most often used for waterproofing flat roofs. The advantage of this material is resistance to wear, moisture and other external influences. In addition, liquid polyurethane can be used in difficult areas of the roof, where another insulator will be difficult to use.

It should be noted that the presented material can be plugged holes and cracks in the old roof. The advantages of such waterproofing are:

- good adhesion;

- fast drying;

- strength;

- availability;

- ease of use;

- resistance to the negative influence of the external environment;

- ecological cleanliness.

Decorative products from the presented material: advantages and features of use

I must say that the material presentedused to produce interior decoration items. For example, decorative polyurethane is used for the production of eaves, ceiling plinths or other products. Very popular is the stucco from the presented substance. It is durable, resistant to mechanical loads, the ability to create non-standard forms. It should be noted that the elements of the decor you can make to order.

The advantages of such products are:

- strength;

- decorative appeal;

- ease of installation;

- ease of care and operation;

- low cost;

- different shades.

I must say that, unlike plaster decorative elements, polyurethane products do not turn yellow over time. In addition to the eaves, you can order the manufacture of columns, pilasters, beams for stairs.

Features and use of foamed polyurethane

The most popular material in construction andrepair is foamed polyurethane. It has low weight, good heat and sound insulation qualities, as well as low cost. It is resistant to steam, moisture, sunlight and temperature changes.

To use such a substance is quite simple.You just need to put it on the desired area. However, it is necessary to take into account the fact that the material is able to increase in size. The advantage of the substance is good adhesion, the possibility of staining.

In principle, these are all features of the use of the material presented. Good luck!
