Acrylonitrile Butadiene Rubber (NBR), usually shortened to Nitrile, was developed in 1941 as the first oil resistant rubber. Grades with high acrylonitrile content have better oil resistance whereas low acrylonitrile content gives better low temperature flexibility and resilience.
Since its establishment in 2008, Hebei Zhenpeng International Trade Co., Ltd. has accumulated many years of technical experience, and can customize various O-ring varieties and specifications according to the needs of customers. In 2014, we have successfully developed from a factory to a supplier integrating production and trade.
Our company is specialized in producing all kinds of rubber seals, such as O-ring, FKM oil seal, stainless steel PTFE oil seal, rotary seal (hub oil seal, box oil seal), etc., which are mainly used in hydraulic and pneumatic aspects, and widely used in plumbing, hardware, home appliances, medical equipment, machinery, electronics, semiconductor, aerospace, military and other fields The main materials used in our rubber sealing products are NBR, EPDM, FKM, HNBR, silicon, ACM, ffkm, etc.
Now our company has advanced and perfect production line, which can provide all kinds of rubber seal products with higher cost performance for our cooperative users, and our company always insists on treating customers with high-quality products and professional services, which has won good comments and trust from customers all over the world.
