SBR 1502 is produced by famous chemical plants in the world and have a wide range of uses in people's lives.
Styrene-butadiene rubbers are produced by a technology of cold emulsion copolymerization and are coagulated by a system of acid and synthetic coagulant. Some grades are solid and some are modified by extender oils. Styrene-butadiene rubbers are stabilized by staining or non-staining antioxidants.Styrene-butadiene rubbers are appropriate for rubber compounds used in the production of car tires and inner tubes, conveyor belts, footwear, cables, hosepipes and various technical rubber articles.Non-staining grades of rubber are appropriate for compounds used in the production of floor coverings, bicycle tires, footwear, children toys, cables, hosepipes and various rubber articles having light color shades.
For the rubber ,the brands are Kumho,LG,Zeon,ENI,Sinopec(Qilu)Zhechen,Iran ,Synthos,Goodyear,Lion,Jsr ,all the russia factory,and Nainit,the grades are SBR 1502,1500,1712 ,1705,1778 ,1723,1783,SKD-ND KBR01 BR1208 PBR1220 NBR 35L 35LM 6240 6250, CR IR2200,BK 1675N IR2200...
We also supply the SBS of CHINA Sinopec brand,like SBS 792 791H 815.
