Hydrogenated Nitrile Butadiene Rubber (HNBR), also known as Highly Saturated Nitrile (HSN), is special class of nitrile undergone hydrogenation process by adding hydrogen atoms to "saturate" the butadiene segments of the carbon polymer. It has good chemical resistance, high thermal stability and tensile strength. It popular in automotive and oil field applications. However, the hydrogenation process that brings heat resistance also decreases low temperature elasticity and causes creep.

Hydrogenated Nitrile is suitable for dynamic and static seal of o-rings in the environment containing the following chemicals: Acetamide, Aluminium Chloride, Aluminium Flouride, Cold Gas Ammonia, Ammonium Chloride, Ammonium Nitrate, Ammonium Phosphate, Amyl Borate, Animal Oil, Argon, ASTM Fuel A, ASTM Fuel B, ASTM Oil One, ASTM Oil Three, ASTM Oil Two, Automatic Transmission Fluid, Benzine (Ligroin), Borax Solutions, Boric Acid, Bunker Oil, Butane, Butter, Butyl Alcohol, Calcium Carbonate, Calcium Chloride, Calcium Nitrate, Calcium Sulfide, Carbon Monoxide, Carbonic Acid, Castor Oil, Tung Oil China Wood Oil, Citric Acid, Cod Liver Oil, Coolanol Monsanto, Corn Oil, Creosylic Acid, Crude Oil (Asphalt Base), Cyclohexane, Denatured Alcohol, Diesel Oil, Dow Corning 550, Dow Guard, Elco 28 Lubricant, Ethanol, Ethyl Alcohol, Ethyl Chloride, Ethyl Diamine, Ethylene Glycol, Freon 113, Freon 114, Freon 12, Freon C318, Freon TF, Fuel Oil, Glucose, Helium, Heptane, Petroleum Base Hydraulic Oil, Iodine, Iso Octane, JP 3 MIL-J5624, JP 4 MIL-J5624, JP 5 MIL-J5624, JP 6 MIL-J5624, Kerosene, Animal Fat Lard, Hydraulic Fluid (Phosphate Ester Type) Lindol, Linsed Oil, Liquefied Petroleum Gas (LPG), Mercuric Chloride, Mercury, Methane, Methanol, Methyl Ether, MIL-F-25558 (RJ-1), JP-5 JP-4 JP-3 MIL-J 5624, MIL-R-25576 (RP-1), MIL-S-81087, Mineral Oils, Natural Gas, Neatsfoot Oil, Oleic Acid, Potassium Nitrate, Potassium Sulfate, Producer Gas, Propane, Propanol, Propyl Alcohol, Transformer Oil Pyranol, Red Oil, RJ-1 (MIL-F-25558), RP-1 (MIL-R-25576), Sea Water, Silicone Grease, Silicone Oils, Sodium Bicarbonate, Sodium Carbonate, Sodium Chloride, Soyabean Oil, Steam to 350F, Stoddard Solvent, Tannic Acid, Tartaric Acid, Type A Transmission Fluid, Turbine Oil, Turpentine, Fresh Water, Whiskey.

O-Ring material Hydrogenated Nitrile is usually suitable for static seal in the environment containing Glacial Acetic Acid, Anhydrous Ammonia, Amyl Alcohol, Aromatic Fuel 50%, Askarel Transformer Oil, ASTM Fuel C, ASTM Fuel D, ASTM Oil Four, Bleach Liquor, Brake Fluid, Calcium Hypochlorite, Carbon Tetrachloride, Chlordane, Dichloro-Butane, Di-ester Lubricant MIL-L-7808, Dioxane, Freon 11 (M), Freon 112, Freon 114B2, Gallic Acid, Hydrocyanic Acid, Isobutyl Alcohol, Isopropanol, Isopropyl Ether, Linoleic Acid, Lye, Methyl Bromide, Type 1 Fuel MIL-S-3136, Naphtha, Octyl Alcohol, Oleum (Fuming Sulfuric Acid), Oronite 8200, Oxalic Acid, Rapeseed Oil, Silver Nitrate, Stearic Acid, Sucrose Solutions, Sulfur Hexafluoride, Sulfurous Acid, Tertiary Butyl Alcohol, Tetrabutyl Titanate, Tetraethyl Lead, Varnish, White Pine Tar.

O-Ring material Hydrogenated Nitrile is sometimes ok for static seal but not for dynamic seal in the environment containing chemicals such as Arachlor 1248, Butyl Cellosolve, Dry Chlorine, Wet Chlorine, Methyl Cellosolve, Ozone, Radiation, Triethanolamine, VV-H-910, Wagner 21B Brake Fluid.
