Millable Polyurethane rubber is made from both polyester and polyether polyols. It has outstanding abrasion, oil, oxygen and ozone resistance. It maintains good flexibility at low temperature and exhibits good resistance to compression set.

Millable Polyurethane is suitable for dynamic and static seal of o-rings in the environment containing the following chemicals: Air below 200 C, Ammonium Carbonate, Ammonium Sulfate, ASTM Fuel A, ASTM Oil One, ASTM Oil Three, Borax Solutions, Boric Acid, Calcium Chloride, Calcium Hydroxide, Calcium Sulfide, Carbon Monoxide, Carbonic Acid, Castor Oil, Citric Acid, Cod Liver Oil, Corn Oil, Crude Oil (Asphalt Base), Dow Corning 550, Elco 28 Lubricant, Ethyl Mercaptan, Ethyl Oxalate, Freon 114, Freon 12, Petroleum Base Grease, Helium, Hydrogen Gas, Mercuric Chloride, Mercury, Type 1 Fuel MIL-S-3136, Mineral Oils, Neatsfoot Oil, Gas Nitrogen, Oronite 8200, Cold Oxygen, Ozone, Pine Oil, Potassium Nitrate, Potassium Sulfate, Producer Gas, Silicone Grease, Silicone Oils, Silver Nitrate, Sodium Bicarbonate, Sodium Chloride, Stearic Acid, Tannic Acid, Tartaric Acid, Type A Transmission Fluid, Turbine Oil, Fresh Water.

O-Ring material Millable Polyurethane is usually suitable for static seal in the environment containing Acetylene Gas, Aluminium Chloride, Aluminium Sulfate, Cold Gas Ammonia, Ammonium Chloride, Animal Oil, Arachlor 1248, ASTM Fuel D, ASTM Oil Two, Automatic Transmission Fluid, Bunker Oil, Cyclohexane, Dibenzyl Ether, Ethyl Acetoacetate, Ethyl Cellulose, Ethylene, Ethylene Glycol, Freon 112, Freon 113, Heptane, Hexane, Isopropyl Ether, JP 5 MIL-J5624, Linsed Oil, Petroleum Base Lubricating Oils, Lye, Methyl Acetate, Methyl Alcohol, MIL-F-25656, MIL-G-25760, MIL-H-5606, Naphthalene, N-Hexaldehyde, Oleic Acid, Oxalic Acid, Peanut Oil, Petroleum Oil, Transformer Oil Pyranol, Rapeseed Oil, Red Oil, RJ-1 (MIL-F-25558), Sodium Carbonate, Soyabean Oil, Stoddard Solvent, Sulfur Hexafluoride, Tetraethyl Lead.

O-Ring material Millable Polyurethane is sometimes ok for static seal but not for dynamic seal in the environment containing chemicals such as Alkazene, Aluminium Nitrate, Argon, Benzine (Ligroin), Tung Oil China Wood Oil, Diethylamine, Dow Guard, Ethane, Ethyl Chloride, Formaldehyde, Freon 13, Hydrochloric Acid, JP 3 MIL-J5624, JP 4 MIL-J5624, JP 6 MIL-J5624, Methane, Methanol, JP-5 JP-4 JP-3 MIL-J 5624, MIL-L-25681, Natural Gas, Styrene Monomer, Sulfur Chloride, Wet Sulfur Dioxide Gas.

Millable Polyurethane is not suitable for o-rings exposed in the environment containing chemicals such as Acetaldehyde, Acetamide, Glacial Acetic Acid, Acetic Anhydride, Acetone, Acetophenone, Acetyl Chloride, Acrylonitrile, Aluminium Acetate, Aluminium Flouride, Anhydrous Ammonia, Hot Gas Ammonia, Concentrated Ammonium Hydroxide, Ammonium Persulfate Solution, Amyl Acetate, Amyl Alcohol, Amyl Chloronaphthalene, Aniline, Aniline Oil, Aromatic Fuel 50%, Askarel Transformer Oil, ASTM Fuel B, ASTM Fuel C, ASTM Oil Four, Automotive Brake Fluid, Benzaldehyde, Benzene, Benzene Sulfonic Acid, Benzoic Acid, Benzophenone, Benzyl Alcohol, Bleach Liquor, Bromine Gas, Bromobenzene, Butadiene Monomer, Butyl Carbitol, Butyl Cellosolve, Butyraldehyde, Calcium Carbonate, Carbitol 2, Carbolic Acid (Phenol), Carbon Tetrachloride, Cellosolve, Chloracetic Acid, Chlorinated Solvents, Chlorine Dioxide, Chlorine Trifluoride, Dry Chlorine, Wet Chlorine, Chloroform, Chlorosulfonic Acid, Chrome Plating Solution, Coffee, Coolanol Monsanto, Creosylic Acid, Denatured Alcohol, Diacetone, Diacetone Alcohol, Dibutyl Phthalate, Dichloro-Butane, Di-ester Lubricant MIL-L-7808, Diethylamine Glycol, Dimethyl Formamide, Dimethyl Phthalate, Dioxane, Diphenyl, Dowtherm A, Ethanol, Ethyl Alcohol, Ethyl Benzene, Ethyl Benzoate, Ethyl Chlorocarbonate, Ethyl Diamine, Ethyl Hexanol, Ethyl Pentachlorobenzene, Ethyl Silicate, Ethylene Dichloride, Ethylene Oxide, Ethylene Trichloride, Freon 22, Furan, Furfural, Furfuryl Alcohol, Gallic Acid, General Glycol, Hexyl Alcohol, Hydrazine, Hydrobromic Acid, Gas Hydrobromic Acid, Hydrocyanic Acid, Hydrofluoric Acid, Iodine, Iso Octane, Isobutyl Alcohol, Isopropanol, Isopropyl Acetate, Isopropyl Chloride, Lacquer Solvents, Lacquers, Hydraulic Fluid (Phosphate Ester Type) Lindol, Malathion, Methyl Acrylate, Methyl Bromide, Methyl Butyl Ketone, Methyl Cellosolve, Methyl Chloride, Methyl Ethyl Ketone (MEK), Methyl Isobutyl Ketone (MIBK), Methyl Methacrylate, Methylene Chloride, MIL-F-25558 (RJ-1), MIL-H-7083, Monovinyl Acetate, Nitrobenzene, Nitroethane, Nitrogen Tetroxide, Nitromethane, Nitropropane, N-Octane, N-Pentane, Octyl Alcohol, Oleum (Fuming Sulfuric Acid), 200-400F Oxygen, Phenol, Propanol, Propyl Acetate, Propyl Alcohol, Propylene, Propylene Oxide, 10E Pydraul, 540C 312F 230C Pydraul, 90E 65E 50E 30E Pydraul, 55 (Phosphate Ester) 53 43 Pyrogard 42, Skydrol 500, Steam to 350F, Sulfur Trioxide, Sulfurous Acid, Tertiary Butyl Alcohol, Tertiary Butyl Mercaptan, Tetrabromoethane, Tetrachloroethane, Tetrachloroethylene, Tetrahydrofuran, Tetralin, Toluene, Triethanolamine, Turpentine, VV-H-910, Wagner 21B Brake Fluid, Whiskey, Xylene.
