Physicochemical properties of hydrogenated nitrile rubber O-ring
Hydrogenated nitrile rubber is obtained by selectively hydrogenating butadiene group in nitrile rubber. The performance of hydrogenated nitrile rubber O-ring seals depends on the content of CAN (18% - 50%) and carbon carbon bond saturation. Its main characteristics are: good heat resistance, organic peroxide vulcanized materials can be used continuously for more than 1000 hours at 160 ℃, while NBR loses its continuous use value at 150 ℃; The oil resistance is excellent, and the performance of oil resistance and alcohol based oil resistance is greatly superior to the corresponding NBR and NBR/PVC blends; Low temperature resistance is better than…
