Polyurethane - what is it? Production of polyurethane, products thereof

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

Advantages of the material

The presented material has quite a lot of advantages:

· Resistance to wear, aging and external influences.

High strength.

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

· Possibility of using the substance under high load.

· A wide range of temperatures in which polyurethane (what it is you already know) can be used.

· It is used in many spheres of human life.

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

Durability.

· Affordable cost. This material, whatever characteristics it has, is inexpensive, so any person with an average and even a minimum salary can get it .

· Practicality and multifunctionality.

· No deformation.

· Does not leave traces on the surface with which they interact.

Properties and technical characteristics of the material

The most common material today is polyurethane. What it is, what advantages it has, you already know. Now we will understand the technical characteristics of this substance.

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

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

Features of manufacturing of the presented material

It should be noted that the production of polyurethane can not be called simple. It takes a lot of energy, labor and energy. The process itself occurs by mixing and heat treating several elements: a polyol and an isocyanate. In addition, polyester amines are added to this mixture. The whole process is performed on rather expensive equipment.

It should be noted that raw materials are produced in 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. A lot of products are made from it. For example, in medicine it is used for the production of condoms, which are distinguished by their strength, smoothness, low cost and environmental safety. Also from the presented substance tires for automobile wheels are made. They not only serve much longer rubber, but also leave no traces.

It should be remembered and such products from polyurethane, as sealing rings, bushings, cuffs. This substance is used as a heater. The presented material is also used in the furniture industry for making 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, guiding elements, bandages, lining, pulleys, pipe rails and other items.

Where is polyurethane used in liquid form?

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

It should be noted that the material presented can be filled with holes and cracks in the old roof. Advantages of this waterproofing are:

- good adhesion;

- quick drying;

- strength;

- availability;

- ease of use;

- resistance to negative environmental influences;

- ecological cleanliness.

Decorative articles from the presented material: advantages and peculiarities of use

I must say that the material presented is used for the production of interior decoration elements. For example, decorative polyurethane is used to produce cornices, ceiling skirting boards or other products. Very popular is the stucco from the substance presented. It is strong, resistant to mechanical stress, the ability to create non-standard forms. It should be noted that the decor elements can be made to order.

Advantages of such products are:

- strength;

- decorative appeal;

- Ease of installation;

- ease of care and maintenance;

- low cost;

- Different shades.

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

Features and use of foamed polyurethane

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

Use such a substance is simple enough. You just need to apply it to the required area. However, one must also take into account the fact that the material can grow in size. The advantage of the substance is good adhesion, the ability to stain.

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