CHIMEI
Butadiene rubber
Kibipol® BR is a representative general purpose synthetic rubber produced by Chi Mei Corporation in Taiwan.
Manufacturer introduction
Chi Mei Corporation, headquartered in Tainan, Taiwan, is one of the world’s leading manufacturers of raw materials for plastics and rubber.
Chi Mei Corporation produces a wide range of products, including ABS resin, which has the largest market share in the world, PS resin, and PC resin.
In synthetic rubber products, the company produces BR (butadiene rubber) and S-SBR (Solution styrene-butadiene rubber).
We promise our customers stable quality and supply backed by our 50 years of production and research and development.
In addition to rubber polymers such as high cis-BR, low cis-BR, and S-SBR, we also offer styrene-based TPEs such as SBS.
Main applications
Compared to natural rubber and SBR, BR has superior cold resistance, aging resistance, and abrasion resistance.
And BR also has high elasticity, low dynamic heat generation, and excellent processability such as blendability, high fillability, moldability, and mold flow.
The application is mainly for industrial products such as automobile tires, footwear, rubberized fabric, gaskets, vibration bumpers, and O-rings, It is also used in consumer products such as golf ball cores and as a modifier for polystyrene.
