Polyurethane is an elastic polymer that is used instead of rubber and even some metals, it is often used in mechanisms where there is constant friction. Polyurethane is a unique synthetic polymer material mainly composed of two types of raw materials, isocyanate and polyol, which are derived from crude oil. Polyurethanes can be viscous liquids or solids ranging from highly elastic soft rubbers to hard plastics. Polyurethane, as a structural material, not only replaces metals and rubber, but sometimes even surpasses them in performance properties. Due to their characteristics, polyurethane products are used in conditions of extreme mechanical loads. The hardness of polyurethane can range from 55 to 98 units. by Shore A. Polyurethane material shows resistance to aggressive environments of fuel, technical and mineral oils. This material does not emit components harmful to human health, therefore it is used in food production. The polyurethane plate can be used as: - stamping plate in wood-stamping production; - elastic gasket material, linings for gates, etc.; - lining plate; - shock absorber, damper, compensator, vibration damper; - flexible, elastic and wear-resistant cleaner for conveyor belts; - scraper for rollers; - workpiece for completing parts of machine assemblies and mechanisms. Important features of polyurethane: - high wear resistance; elasticity; strength; tear resistance; immunity to microorganisms (mold); resistance to swelling in oils and liquids.
