Elastomers and their application.

Polyurethane elastomers belong to the group of plastics that are formed as a result of polymerization, and their main chains contain urethane groups. Referred to as PUR or PU, they have many valuable properties. Their advantages and very favorable price make elastomers a material widely used in many industries.

Elastomer properties:
PUR materials are rubber-like materials. From rubber they differ, among others in that they have even better physical and chemical parameters than it does. In addition, it is possible to shape the properties of polyurethane elastomers in a very wide range. In practice, this means that PU is a universal material.

Its biggest advantages include a high exploitation index, which it achieves thanks to its very high resistance to:

the action of chemical substances such as gasoline, solvents, oils, greases, sulfuric acid, caustic soda or salt water; in addition, PU products can work in an environment whose pH is between 5 and 12,
moisture and other adverse weather conditions,
abrasion,
stretching, tearing and cracking - products made of PUR plastic successfully withstand temperatures from -40 ° C to 80 ° C,
aging.
What other features do polyurethane elastomers stand out? It is certainly worth mentioning here that there are:

self-extinguishing
plates,
non-marking,
six times lighter than steel.
In addition, products made of PUR material have excellent vibration damping properties and can be used in both wet and dry conditions. Finally, they are distinguished by a smooth and shiny surface and a wide range of hardness, which does not preclude maintaining significant elongation.

What is the use of PUR plastics?
Polyurethane elastomers are commonly used, among others in the machinery, chemical and textile industries. As a rubber-like material, with properties much better than those of the rubber itself, it is an excellent material for the production of such products as:

gaskets,
membranes,
printing rollers,
bicycle inner tubes,
industrial vehicle wheels,
scrapers
drive belts, press stops and clutches for various types of industrial machines,
rollers, anti-vibration pads and other damping elements,
car shock absorbers.
As you can see, the role of polyurethane elastomers in industry is significant, and the range of their use is very wide.
