Products
High temperature resistant oil resistant rubber compound
Description
The material is modified with hydrogenated nitrile rubber as the base material. It is a product designed for the production of rubber products. It is widely used in some rubber products factories. It has excellent physical properties, stable process and low price. It is an alternative to acrylate rubber. The ideal product for the material. The oil seal oil seal grease, lubricating oil, engine oil and other sealing medium prepared by the rubber compound have no leakage after being tested by the National Seal Testing Center at 150 ° C (oil temperature) × 480 h and line speed 22 m·s -1 , which meets the national standard.
Use
It can be used to manufacture rubber and oil resistant products for petroleum, chemical, automotive and other industries.
