Hydrogenated Nitrile (HNBR) O-Rings | ESP International

Hydrogenated Nitrile (HNBR) O-Rings. Hydrogenated Nitrile comes from adding hydrogen to the nitrile molecular chain to make it more stable. The addition of hydrogen reduces the number of carbon-carbon double bonds, making it less reactive. In comparison with NBR, HNBR has better abrasion resistance, tear resistance, high-temperature properties ...
