What is an HNBR O-ring?
HNBR (hydrogenated nitrile butadiene rubber) is obtained by fully or partially hydrogenating the double bonds in nitrile butadiene rubber with hydrogen to single bonds. In comparison with NBR O-rings, HNBR O rings have better properties in terms of oil resistance, temperature resistance, and strength. It is more resistant to ozone and aggressive substances and can be used from -40 °C to +165 °C (with peaks up to +190 °C).
The advantages of O-rings HNBR:
- Resistant to hydraulic fluids based on mineral oil
- Resistant to animal and vegetable fats
- Resistant to diesel, ozone, acid gas, diluted acids, and bases
- Resistant to new organic oils (organic oils)
- Suitable for high dynamic loads and has good wear resistance
- Mechanically strong
- Good compression set / good hot crack / good ozone and aging resistance
- Resistant to high-energy radioactive radiation
- Good resistance to hot water and steam
- Temperature resistant to long-term +150 °C with higher peaks
- Good resistance to various media
- Excellent heat and oxidation resistance
- Applicable in water and steam
- Temperature range from -40 °C to +150 °C
- Excellent resistance to liquids from motor vehicles (engine oil, coolant, fuel, etc.)
The disadvantages of HNBR Orings:
- Significantly more expensive
- Not resistant to chlorinated hydrocarbons
- Not resistant to polar solvents (ketones, eaters and esters)
- Not resistant to strong acids
