NBR
(Acrylonitrile Butadiene Rubber)
1. Product Introduction
KNB is a cold emulsion copolymer of acrylonitrile and butadiene. It
has superior resistance to hydrocarbons, solvents, vegetable oils, acid,
alkalis, and many other liquids and gases. Resistant to abrasion, heat,
water, and flexing are also provided by our NBR.

KNB is suitable material for injection molding of rubber products
with various shape, and it can also be used with a relatively large amountof plasticizer.

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.
