HYDROGENATED NITRILE (HNBR, HSN)
Hydrogenated Nitrile (HNBR) is a synthetic polymer that results from the hydrogenation of nitrile rubber (NBR). Superior mechanical characteristics, particularly high strength, helps reduce extrusion and wear.
Heat resistance:
Cold flexibility:
- Down to approximately -48°C (-55°F)
Chemical resistance:
- Aliphatic hydrocarbons
- Vegetable and animal fats and oils
- HFA, HFB and HFC hydraulic fluids
- Dilute acids, bases and salt solutions at moderate temperatures
- Water and steam up to 149°C (300°F)
- Ozone, aging and weathering
Not compatible with:
- Chlorinated hydrocarbons
- Polar solvents (ketones, esters and ethers)
- Strong acids
