Hydrogenated Nitrile Butadiene Rubber (HNBR) is a highly saturated elastomer obtained by the special hydrotreating of Nitrile butadiene rubber ( NBR )
1. HNBR excellent oil resistance: good resistance to fuel oil, lubricating oil and aromatic solvent
2. Heat Resistance: 160oC ( HNBR Working Temperature: -40oC ～ 160oC ) Good Ozone Resistance ; HNBR Gasket will not out of shape after long-term compression.
3. Excellent chemical corrosion resistance Freon R134a; Below 150℃ hot water; Low concentration of inorganic acids such as hydrochloric acid, phosphoric acid; Low concentration of alkali such as sodium hydroxide, ammonia; Low concentration salts such as sodium chloride, sodium carbonate; Alcohols such as methanol, ethanol. Below 5% H2S
4. Excellent mechanical and physical properties High strength; High tear Resistance; Wear-resisting Property HNBR is one of excellent overall performance rubber
HNBR Disadvantage: Expensive
Hydrogenated Nitrile Butadiene Rubber（HNBR） is currently widely used in oil fields, automobile industry and so on. In the very harsh conditions of use, Hydrogenated Nitrile Butadiene Rubber （HNBR）has a good performance, and increasingly large number of use
