We produce the PU Springs with Polyester type prepolymer and MOCA.
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.Highlight 1It
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.
