POLYBUTADIENE RUBBER
(HIGH cis BR)
1. Product Introduction
Polybutadiene Rubber
is a single-polymer produced by polymerization of 1,3-butadiene.
It has 3 chemical bond structures of cis-1,4, trans-1,4, and vinyl.
Also it is divided into High cis BR and Low cis BR according to the configuration of cis-1,4.

High cis BR is a product that has a configuration of more than 94% cis-1,4. This product has excellent abrasion resistance, resiliency, age resistance, and water-resistance. In addition, it has a very low 2nd transition temperature (Tg) of -100C, therefore it is the most widely used synthetic rubber along with SBR.

KBR 01 and 01L are used in tires, footwear, belts, rubber hoses, and other mechanical rubber products. Aromatic oil is added to KBR31, and it is mainly used for conveyer belts and tires. Especially, it shows excellent performance in snowtire treads.
