Title:
FLUORINE-CONTAINING ELASTOMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/042510
Kind Code:
A1
Abstract:
This fluorine-containing elastomer composition is obtained by blending 0.2-0.9 parts by weight of quinacridone and 0.2-5 parts by weight of a bis-amidoxime compound or 2,2-bis(3-amino-4-hydroxyphenyl)hexafluoro propane, with respect to 100 parts by weight of a fluorine-containing elastomer having a copolymerization compositional makeup comprising (A) 60.0-80.0 mol% of tetrafluoroethylene, (B) 19.8-35.0 mol% of perfluoro(lower alkyl vinyl ether) or perfluoro(lower alkoxy lower alkyl vinyl ether), and (C) 0.2-5.0 mol% of a perfluoro unsaturated nitrile compound. In a case where a cyano group is used as a crosslinkable group in the fluorine-containing elastomer, a vulcanizate of the fluorine-containing elastomer composition exhibits excellent heat resistance even when being placed in a high temperature condition of at least 300℃ and used in a plasma irradiation condition.
