Use less relative NBR hydrogenated nitrile rubber, nitrile rubber seals type O sealing ring is also common in, but also for the comprehensive performance of hydrogenated nitrile rubber is better, so often used in type O sealing ring, the seal is to introduce the main process and characteristics of hydrogenated nitrile type O sealing ring. Hydrogenated nitrile rubber seals is conducted by nitrile rubber after the special hydrotreating and get a highly saturated elastomer. Hydrogenated nitrile rubber is NBR hydrogenation unsaturated double bond, general points fully saturated with a small amount of double bond. Fully saturated cannot use sulphur vulcanization with peroxide vulcanization; A small amount of double bond residue can use sulphur vulcanization. Hydrogenated nitrile type O sealing ring has good oil resistance, resistance of fuel oil, lubricating oil, aromatic solvent resistant to good. Due to its highly saturated structure, hydrogenated nitrile type O sealing ring has the following characteristics: 1, good heat resistance performance, is generally - 60 to 180 degrees; 2, excellent chemical corrosion resistance, freon, acid, alkali has good resistance to patience; 3, excellent ozone resistance, higher compression permanent deformation resistance. 4, high strength, high tear performance, wear-resisting performance, etc. The above are the main process of hydrogenated nitrile type O sealing ring and the main characteristics, the conditions are different, but as a result of each product use the material also can have differences. Seal 17 years of development, production experience, has a group of professional technical engineers, can according to customer demand for the customer design the appropriate hydrogenated nitrile type O sealing ring, welcome to map design.
