Product Description

                                         Styrene Butadiene Rubber / SBR1502


SBR 1502 is one of the most widely used synthetic rubber.
Low temperature emulsion polymerized technique. Its wear resistance,aging resistance,ozone resistance,water-proofing,air tightness and homogenous are much better.
