TECHNICAL DATA SHEET
FOR
STYRENE BUTADIENE RUBBER (SBR)

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 Qilu Company has a production capacity of 250kta. The products are respectively brand-named SBR1500, SBR1502, SBR1712, etc.
