Styrene Butadiene Rubber, Brand Name : SINOPEC

We are offering styrene butadiene rubber.
The two types of sbr15021712 were widely used in tyres, cycle tire, rubber overshoes, plastic hosoe tapes, conveyors, rubber tubes, black sole, rubber lines, rice polishing rollers, extruded products, medical products and other colorful or light- colored rubber products.
compared with natural rubbers, it has excellent wear resistance, natural aging resistance, ozone resistance, water proof property, air tightness and homogeneity, and can be mixed with natural rubber at any ratio.
