Product Overview

Description








Styrene Butadiene Rubber / SBR 1502

Specification:












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.
