Liquid NBR
Liquid acrylonitrile-butadiene rubber
We deal in L-NBR (Liquid NBR) manufactured by Jiansheng Rubber and Plastic Technology Co., Ltd. in China.
L-NBR is a liquid rubber with or without other functional groups, whose main chain is composed of butadiene and acrylonitrile, and is viscous under room temperature environment. With its average molecular weight of less than 10,000, it is a low molecular type liquid reinforcer, plasticizer, and rubber softener. Viscous liquid rubber developed based on NBR is odorless, slightly yellow and transparent. Combined with phenolic resins, it improves the brittleness of resins and enhances flexibility and heat resistance.
Manufacturer introduction
Jiansheng Rubber and Plastic Technology Co., Ltd. is a synthetic rubber manufacturer established in 2008 and headquartered in Hengshui, Hebei Province, China. We deal in liquid NBR as well as powder NBR for PVC modification and friction materials.
Main applications
NBR is made into packing, oil seals, hoses, conveyor belts, and more by taking advantage of its oil resistance, and finally used for automobile parts and various industrial products.
