Overview
SBR is produced with the patent technique licensed from Zeon, Japan. The Whole set of unit was designed and provided by Mitsubishi Heavy Industries, Ltd. With butadiene and styrene as main feedstock, SBR are produced by low temperature (5 ℃) emulsion polymerization procedures. Compared with natural rubber, SBR possess outstanding abrasion-, ageing-, ozone-, water-resistance, air-tightness and homogeneity characteristics and could be blended with natural rubber in any proportion.
Production plant
The Styrene Butadiene Rubber plant at the KUMHO Company has a production capacity of 400kta. The products are respectively brand-named SBR1500, SBR1502, SBR1712, etc.

Packaging
SBR is packed in internal PE coated plastics woven bags with 35 kg each for net
SBR should be stored in dry and well ventilated warehouse at ambient temperature. Precautions should be taken against sunburn or rainwater in transportation and handling. Vehicle should be clean and damaged packaging materials should be prevented from entering.
