Perfluoropolyether-based rubber composition, cured object obtained therefrom, and product including same

Abstract

A perfluoropolyether-based rubber composition which gives cured objects excellent in terms of heat resistance, low-temperature resistance, organic-solvent resistance, and acid resistance, the rubber composition being characterized by comprising (a) a linear perfluoropolyether compound having a number-average molecular weight of 1,000-100,000 and including at least two azido groups in the molecule and a divalent perfluoroalkyl ether structure in the main chain and (b) a linear perfluoropolyether compound having at least three ethynyl groups in the molecule.
