Glossary » Design » Oring » Material » Aflas

Aflas is the tradename for a unique fluoroelastomer based upon an alternating copolymer of tetrafluoroethylene and propylene ("TFE/P"). The elastomer, when properly formulated, can be excellent heat resistance, chemical (acid and base) resistance, high electrical resistivity. It is however not suitable for sealing certain oils and solvants.

Aflas is suitable for dynamic and static seal of o-rings in the environment containing the following chemicals: Acetamide, Acetic Anhydride, Acetyl Chloride, Ammonium Carbonate, Ammonium Chloride, Ammonium Nitrate, Aniline, ASTM Oil One, ASTM Oil Three, Automatic Transmission Fluid, Benzaldehyde, Benzyl Alcohol, Benzyl Chloride, Bleach Liquor, Brake Fluid, Bromine Gas, Calcium Chloride, Calcium Hydroxide, Calcium Hypochlorite, Calcium Nitrate, Calcium Sulfide, Carbon Disulfide, Castor Oil, Wet Chlorine, Chlorosulfonic Acid, Chromic Acid, Citric Acid, Creosylic Acid, Cyclohexane, Dichloro-Butane, Diesel Oil, Diphenyl, Dowtherm A, Ethyl Alcohol, Ethyl Benzene, Ethylene Dichloride, Ethylene Glycol, Formaldehyde, Furfural, Hexane, Hydrazine, Hydrochloric Acid, Hydrofluoric Acid, Hydrogen Peroxide, Iso Octane, Kerosene, Linsed Oil, Methyl Alcohol, Methyl Cellosolve, Methyl Chloride, MIL-H-5606, Naphtha, Naphthalene, Naphthalenic, Nitric Acid, Nitrobenzene, Nitroethane, Oleic Acid, Phenol, Pine Oil, Potassium Nitrate, Propyl Alcohol, Skydrol 500, Sodium Carbonate, Sodium Chloride, Sodium Hydroxide, Steam to 350F, Stearic Acid, Wet Sulfur Dioxide Gas, Sulfuric Acid (Concentrated), Sulfurous Acid, Triethanolamine, Fresh Water.

O-Ring material Aflas is usually suitable for static seal in the environment containing Benzene, Ethyl Benzoate, Automotive Gasoline, Heptane, Methyl Propyl Salicylate, Styrene Monomer, Turpentine, Xylene.

Aflas is not suitable for o-rings exposed in the environment containing chemicals such as Glacial Acetic Acid, Acetone, Carbon Tetrachloride, Chloroform, Dioxane, Ethyl Acetoacetate, Freon TF, Isopropyl Ether, Lacquer Solvents, Methyl Ethyl Ketone (MEK), Methyl Isobutyl Ketone (MIBK), Toluene.
