When we customize rubber seals, we must first understand the performance of the relevant rubber and whether it is applicable. Today, Haisheng Rubber takes you to know about nitrile rubber.
Nitrile rubber has very good oil resistance, its oil resistance is second only to polysulfide rubber and fluorine rubber, and it has very good abrasion resistance and air tightness. But nitrile rubber also has its limitations. Its disadvantage is that it is not resistant to ozone and aromatic, halogenated hydrocarbons, ketones and ester solvents, and is not suitable for insulation materials. Nitrile rubber has better heat resistance than styrene-butadiene rubber and neoprene rubber, and can work for a long time at a high temperature of 120 ° C. Airtightness is second only to butyl rubber. The properties of nitrile rubber are affected by the content of acrylonitrile. As the content of acrylonitrile increases, the tensile strength, heat resistance, oil resistance, air tightness, and hardness of nitrile rubber increase, but the elasticity and cold resistance decrease.
Nitrile rubber is mainly used to make oil-resistant products, such as oil-resistant pipes, tapes, rubber diaphragms, and large oil sacs. It is often used to make various oil-resistant molded products, such as O-rings, oil seals, leather bowls, diaphragms, valves, bellows , Hoses, seals, foaming, etc., also used to make rubber sheets and wear-resistant parts.
The skeleton oil seal is made of high-quality nitrile rubber and steel plate, and the quality is stable. The silicone rubber seal has a long airtight service life. Nitrile rubber frame oil seals are widely used in engines, shock absorbers, transmissions and other places of automobiles, motorcycles, tractors, water pumps and other machinery.
