Material Notes:
Description: BR1208 is high cis- 1,4 polybutadiene polymer produced by a solution polymerization process employing a stereospecific catalyst to control microstructure, molecular weight and molecular weight distribution. This grade is stabilized with a non- staining, non- discoloring antioxidant allowing for its physical property persistence during storage and application. BR1208, having very high cis content more than 97%, have a good abrasion resistance, flex- cracking resistance, resilience and low temperature properties. In addition, BR1208 has an excellent building tack, a good roll processability and white color.Application: BR1208 is used in tire tread, carcass compounds, shoe sole, V- belts, conveyor belt coverings, hose and tube covers, solid golf balls and various industrial products.CAS No: 9003-17-2Information provided by LG Chemical
