Title:
FLUORINE-CONTAINING ELASTOMER AND VULCANIZABLE COMPOSITION THEREOF
Document Type and Number:
WIPO Patent Application WO/2013/172151
Kind Code:
A1
Abstract:
A four-component copolymer fluorine-containing elastomer which has a copolymer composition composed of (A) 2.0-8.0% by mole of vinylidene fluoride, (B) 60.0-70.0% by mole of tetrafluoroethylene, (C) 35.0-25.0% by mole of a perfluoro(lower alkyl vinyl ether) or a perfluoro(lower alkoxy lower alkyl vinyl ether) and (D) 0.2-3.0% by mole of a perfluoro unsaturated nitrile compound, while having a Mooney viscosity ML1+10 (at 121°C) of 65-110; and a vulcanizable fluorine-containing elastomer composition in which 0.2-5 parts by weight of a bisamidoxime compound is blended per 100 parts by weight of the fluorine-containing elastomer. A sealing material which is obtained by vulcanizing and molding this fluorine-containing elastomer composition exhibits low adhesion to a metal at higher temperatures, specifically at 150°C, while having excellent compression set resistance, excellent plasma resistance and the like.
