People who are interested in modern construction or manufacturing often come across a material such 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, which is widely used in various areas of our life: construction, medicine, heavy, footwear or clothing industries. Naturally, this substance is synthetic. It has a lot of benefits, which you will now learn about.
Material Values
The presented material has quite a lot of advantages:
· Resistant to wear, aging and external influences.
High strength.
· It is possible to change the level of elasticity of the material.
· Ability to use the substance under high load.
Wide temperature range in which polyurethane (what you already know) can be used.
Applied in many areas of human life.
Sealants, clothing, insulation, shoes, pipes and other products that are used in everyday life are made from it.
Durability.
Availableprice. This material, no matter what characteristics it has, is inexpensive, so anyone with an average and even minimum salary can purchase it.
Practicality and versatility.
No deformation.
· Does not leave marks on the surface with which they interact.
Material properties and specifications
The most common material today is polyurethane. What it is, what advantages it has, you already know. Now let's deal with the technical characteristics of this substance.
So, the presented material can safely work in an aggressive environment, while its qualitative properties practically do not change. In addition, the substance is perfectly exploited in a fairly wide temperature range: from -60 to +80 degrees. Sometimes it can be heated to 120o, but this process should not last long, otherwise the material will simply collapse.
The polymer is able to withstand heavy loads, is less subject to aging than other substances. It is resistant to wear, moisture, temperature extremes, sunlight, s alt, organic solvents. Polyurethane (what it is, you already know) is considered a very durable material. At the same time, its elasticity can be programmed during the production process. This material may have different characteristics, on which the scope of its application depends. It should be noted that polyurethane may consist of one or more components.
Production featuressubmitted material
It should be noted that the production of polyurethane is not easy. It takes a lot of effort, work and energy. The process itself takes place by mixing and heat treatment of several elements: polyol and isocyanate. In addition, polyesteramines are also added to this mixture. The whole process is carried out on rather expensive equipment.
It should be noted that the raw materials are produced in a few countries: Russia, Germany, USA and Italy. The presented material is made and processed in several ways: casting, pressing, extrusion.
Which products are made from this material?
Polyurethane is a very common material. A lot of products are made from it. For example, in medicine, it is used to produce condoms, which are durable, smooth, low cost, and environmentally friendly. Tires for automobile wheels are also made from the presented substance. Not only do they last much longer than rubber ones, but they also leave no marks.
It should also be remembered that polyurethane products such as o-rings, bushings, cuffs. This substance is used as a heater. The presented material is also 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.
From this material are also produceda variety of suction cups, guides, bandages, linings, pulleys, pipe rails and other items.
Where is liquid polyurethane used?
I must say that this material can be used in different forms: liquid, foamed 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 applied to difficult areas of the roof, where it would be difficult to use another insulator.
It should be noted that the presented material can be used to close up 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
It must be said that the presented material is used for the production of interior decoration elements. For example, decorative polyurethane is used for the production of cornices, ceiling moldings or other products. Very popular is stucco molding from the presented substance. It is distinguished by its strength, resistance to mechanical stress, the ability to create non-standard shapes. It should be noted that you can make decorative elements onorder.
The advantages of such products are:
- strength;
- decorative attraction;
- ease of installation;
- ease of maintenance and operation;
- low cost;
- different shades.
It must be said that, unlike plaster decorative elements, polyurethane products do not turn yellow over time. In addition to cornices, you can order the production of columns, pilasters, beams for stairs.
Features and uses of polyurethane foam
The most popular material in construction and repair is polyurethane foam. It has a low weight, good heat and sound insulation qualities, as well as low cost. It is resistant to steam, moisture, sunlight and temperature extremes.
Using such a substance is quite simple. You just need to apply it to the desired area. However, one must also 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 the features of using the presented material. Good luck!
