ChenGuang FPM 2461 Fluoroelastomer Terpolymer Gum
Categories:	Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer
Material Notes:	Molecular formula: -{-(CF2-CH2)65-(CF2-CF2)20-[CF2-CF(CF3)]15-}n-- Properties: Excellent resistance to high temperature Working for long period under 275°C. Working for short period at 320°C. Excellent resistance to chemical mediums. Good stability against organic liquid(oils, fuels, solvents, hydraulic oils, etc.),inorganic acids, highly-concentrated H2O2 and other oxidants. Much better than other rubbers Not good resistance to M.W. ketones, esters, some ethers, NH3,NH4+,HF Good mechanical properties, insulating properties, corrosion resistance Common cold resistance Brittle point -35°C ~-50°C ,various with formulation and thickness of the products; the thicker, the brittle point higher. Applications: Wildly used in aviation, automobile, petroleum, and chemical industries, etc. as sealing material, to resist high temperature, corrosion, oils(especially di-ester oils, silicate ester, etc.).Usually be made into sealing rings, sealing bowls, sealing tubes, and so on. Besides, used in fabric coating to resist heat and /or corrosion. Information provided by ChenGuang Research Institute of Chemical Industry
