1. the first process of nitrile rubber is made of butadiene and acrylonitrile by emulsion polymerization; Hydrogenated nitrile butadiene rubber is processed on the basis of nitrile butadiene rubber, a highly saturated elastomer obtained by special hydrogenation treatment of nitrile butadiene rubber.
2. heat resistance, the use of conventional nitrile rubber temperature is 100℃, special formula can be used at 120℃; The conventional use temperature of hydrogenated nitrile rubber is 150 ° C, which can be higher, depending on the formula and raw rubber.
3. comprehensive Although nitrile rubber oil resistance, heat resistance, wear resistance is better, but hydrogenated nitrile rubber compared to nitrile rubber has better heat resistance, cold resistance and wear resistance, higher tensile strength, comprehensive performance is better, but the price is also more expensive than nitrile rubber O-type sealing ring.
Nitrile rubber O-type seals are generally used in hydraulic and pneumatic systems, while hydrogenated nitrile rubber O-type seals are mainly used in environmentally friendly air conditioners and some products with relatively high wear and temperature resistance.
