CROSSLINKABLE FLUORINE RUBBER COMPOSITION, FLUORINE RUBBER MOLDED ARTICLE, AND METHOD FOR PRODUCING SAME |
摘要 |
A crosslinkable fluororubber composition containing: a fluororubber (A); and a fluororesin (B), wherein the fluororesin (B) is a copolymer (B1) consisting of tetrafluoroethylene units (a) and hexafluoropropylene units (b) or a copolymer (B2) containing tetrafluoroethylene units (a), hexafluoropropylene units (b), and polymerized units (c) derived from a monomer copolymerizable with tetrafluoroethylene and hexafluoropropylene, the copolymer (B1) satisfies the condition that the ratio (a)/(b) is (80.0 to 87.3)/(12.7 to 20.0) on a molar basis, and the copolymer (B2) satisfies the condition that the ratio (a)/(b) is (80.0 to 90.0)/(10.0 to 20.0) on a molar basis, and the ratio (c)/{(a)+(b)} is (0.1 to 10.0)/(90.0 to 99.9) on a molar basis. |

1. A crosslinkable fluororubber composition comprising:
a fluororubber (A); and a fluororesin (B), wherein the fluororesin (B) is a copolymer (B1) consisting of tetrafluoroethylene units (a) and hexafluoropropylene units (b) or a copolymer (B2) comprising tetrafluoroethylene units (a), hexafluoropropylene units (b), and polymerized units (c) derived from a monomer copolymerizable with tetrafluoroethylene and hexafluoropropylene, the copolymer (B1) satisfies the condition that the ratio (a)/(b) is (80.0 to 87.3)/(12.7 to 20.0) on a molar basis, and the copolymer (B2) satisfies the condition that the ratio (a)/(b) is (80.0 to 90.0)/(10.0 to 20.0) on a molar basis, and the ratio (c)/{(a)+(b)} is (0.1 to 10.0)/(90.0 to 99.9) on a molar basis. |
