Title:
FLUORINE RUBBER COMPOSITION AND FLUORINE RUBBER CROSSLINKED BODY
Document Type and Number:
WIPO Patent Application WO/2018/225487
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a fluorine rubber composition which exhibits excellent adhesion properties, exhibits an excellent permanent compression set in a steam environment, and prevents changes in the hardness thereof in a steam environment; and a fluorine rubber crosslinked body. The present invention solves the problem by providing a fluorine rubber composition which contains a ternary fluorine rubber polymer comprising vinylidene fluoride, perfluorovinyl ether, and tetrafluoroethylene, contains a vinyl ethoxysilane reaction product of a silica-aluminum silicate, and contains hydrotalcite, but does not substantially contain magnesium oxide and calcium hydroxide, the fluorine rubber composition being characterized in that relative to 100 parts by weight of the ternary fluorine rubber polymer, the content of the vinyl ethoxysilane reaction product of the silica-aluminum silicate is 2-55 parts by weight, and the hydrotalcite content is 0.5-10 parts by weight.
