Physical Properties of Neoprene Compound.
Neoprene Bearing Pads,neoprene bridge bearings, laminated
elastomeric bearings,seismic isolators etc generaly known as
bearing pads in the construction industry are manaufactured by
us. Bearings are molded from a mixed rubber compound sheets of
high-grade virgin Neoprene - Polychloroprene Grade- 2 elastomer-
with carbon black and chenicals to formed into a synthetic rubber
compound to match AASHTO M 251 Specifications in
neoprene(polychloroprene).
