It is widely used as Puncher Spring. Compared with metal or normal rubber springs, PU puncher spring is much better in performance, quality stability and working life. The finish products are also with better size accuracy. It improves the production efficiency. PU springs are widely used on Auto production lines as mould spring, puncher spring.Highlight1It 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 85.2It could be cast into practically any shape, size or complex geometry desired wheels, gears, O rings, gaskets, tires, roller blades, skate boards etc.3It can be formulated with high resistance to stresses and it tends to maintain shape and mechanical properties aster fatigue stressing.4Casting Polyurethane maybe pigmented to resist degradation by elevated atmospheric oxygen and ozone atmospheric concentrations.5Many 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.6Casting polyurethane parts can be made flame resistance by incorporating flame retardants into their formulas.7Polyurethane 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.
