Product Description
Cast polyurethanes are a diverse and versatile group of materials that are known for abrasion resistance; chemical resistivity; stability in water; ease of processing and relative low cost; Cast polyurethanes are found in almost every industry; Molds for cast urethanes are relatively inexpensive and can be made from a variety of materials;Cast polyurethanes are a good substitute for a number of materials where improved performance is required; Urethanes can be made as soft as gum rubber or as hard as a golf ball; In fact; most golf balls are polyurethane!Cast polyurethanes are elastomers and are created by the reaction of a prepolymer which contains reactive isocyanate groups and a curative which contains hydroxyl or amine groups; In their simplest form; these two components; the prepolymer and curative are the only chemicals in the mix; The mixture is then poured into a heated mold where the components react to form a solid elastomeric piece;Highlight1; It is the most versatile; toughest; abrasion resistance elastomer available; It is as soft as Shore A durometer 10 and hard as Shore D scale durometer 85;2; It could be cast into practically any shape; size or complex geometry desired wheels; gears; O rings; gaskets; tires; roller blades; skate boards etc;3; It can be formulated with high resistance to stresses and it tends to maintain shape and mechanical properties aster fatigue stressing;4; Casting Polyurethane maybe pigmented to resist degradation by elevated atmospheric oxygen and ozone atmospheric concentrations;5; Many cast polyurethane elastomers compounds remain flexible at extreme low temperatures and possess outstanding resistance to thermal shock; Low temperature resistance of polyurethanes make cast parts very practical in extreme arctic conditions;6; Casting polyurethane parts can be made flame resistance by incorporating flame retardants into their formulas;7; Polyurethane can be cast with coefficients of friction varying from very low; for items like bushings; bearings or wear strips; or very high; for items like tries or rollers;In general; designing for casting polyurethane is identical to designing for any plastic; molded or injection molded; Our pepson company could produce any parts basing on clients requirements like drawings or samples etc;
