Butadiene Rubber (BR) – High & Low CIS

Polybutadiene Rubber (BR), the most elastic rubber type, is a polymerized butadiene built up by chemically linking several molecules of butadiene to form giant molecules, or polymers. Polybutadiene Rubbers (BR) are made either with high cis content (95 to 97 percent) or with only 35 percent cis content along with 55 percent trans and 10 percent side vinyl.
