Polyurethane seals is one of the most commonly used elastomer in most of the industries, when high levels of abrasion are present. This abrasion resistance is combined with high load & impact bearing capabilities that make polyurethane the material of choice for a number of machines and other engineering products. Pu seals:- hydraulic & pneumatic seals like piston seals, rod seals & wiper seals are available in all standard sizes Advantages : Excellent elasticity Low compression set Good chemical resistance High resistance to water Good resistance to heat and low temperature Good resistance to ozone and weather aging
