(A) A linear fluoropolyether compound having at least two alkenyl groups in one molecule and having a perfluoropolyether structure in a main chain, (B) an organosilicon compound having at least two silicon-bonded hydrogen atoms in one molecule and all of the silicon atoms bonded to hydrogen atoms bonded to a benzene ring, (C) containing a hydrosilylation reaction catalyst A curable fluoropolyether rubber composition. [Effect] The cured product of the curable fluoropolyether rubber of the present invention is excellent in heat resistance, chemical resistance, solvent resistance, mold release, water repellency, oil repellency, weather resistance, etc., as well as acid resistance and resistance. It gives a cured product with excellent alkalinity and can be used for a wide range of molding applications.For example, sealing materials for semiconductor manufacturing equipment, automobiles, O-rings for aircraft, diaphragms, sealing materials, roll materials for copiers, secondary batteries and It is useful as a material for constituting an electrode of a fuel cell. |
