Description

Btadiene Rubbersynthetic rubber widely employed in tire treads for trucks and automobiles. It consists of  polybutadiene , an elastomer (elastic polymer) built up by chemically linking multiple molecules of butadiene to form giant molecules, or polymers. The polymer is noted for its high resistance to abrasion, low heat buildup, and resistance to cracking.
