Good chemical resistance to mineral oils and greases, hydraulic oils H, HL, HLP, non-inflammable hydraulic pressure fluids HFA, HFB, HFC to approx. The temperature application range is from -30☌ to +150☌. HNBR has a good resistance to some refrigerants. The media resistance compares to that of NBR. It leads to considerable improvement in resistance to heat, ozone and ageing, and gives it very good mechanical properties, e.g. HNBR is obtained by fully or partially hydrogenating NBR. +80☌, excellent resistance to weathering, ozone and ageing, very low gas permeability (and therefore excellent for vacuum application) and resistance to a wide range of chemicals.
+150☌, fuels, non-flammable hydraulic pressure fluids HFD, aliphatic, aromatic and chlorinated hydrocarbons, water to max. Good chemical resistance to mineral oils and greases, synthetic oils and greases, engine, transmission and ATF oils to approx. EPDM materials are totally unsuitable for use with all mineral oil products (lubricants, fuels). Good resistance to hot water and steam, detergents, caustic potash solutions, silicone oil and greases, many polar solvents, and many diluted acids and chemicals, along with a high level of ozone resistance.
