Synthetic Rubber / SBR1502
SBR 1502 is a co-polymerization of butadiene and styrene emulsions, which does not require special mastification. This product is a general purpose rubber and is compatible with other general rubber types. It is used in industry and in non-coloured technical rubber products manufacture. SBR 1502 is also used in automobile tires for lining of light side-frames.
