HNBR Property & Hydrogenated Nitrile Butadiene Rubber Performance

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
