The invention provides a curable fluoroelastomeric composition comprising: (i) a fluoropolymer comprising at least one cure site monomer that comprises at least one cyano group; (ii) a cure system comprising a functionalized biphenyl-based compound and at least one of: a dioxime compound represented by the formula (I): HON&#x2550;R&#x2550;NOH 

Oxygen plasma-resistant composition characterized by low sticking, and related methods

A curable fluorine-containing elastomer composition is described which includes a first curable perfluoropolymer comprising tetrafluoroethylene, a first perfluoroalkylvinyl ether and at least two cure site monomers, each having at least one cure site, wherein tetrafluoroethylene is present in the first curable perfluoropolymer in an amount of at least about 50 mole percent; a second curable perfluoropolymer comprising tetrafluoroethylene, a second perfluoroalkylvinyl ether and at least one second cure site monomer having at least one cure site, wherein the second curable perfluoropolymer comprises fluoroplastic particles therein; and at least two curatives. Cured compositions and molded articles formed from such compositions are also disclosed.

Fluorine-containing elastomer compositions suitable for high temperature applications

A curable fluorine-containing elastomer composition is described which includes a first curable perfluoropolymer comprising tetrafluoroethylene, a first perfluoroalkylvinyl ether and at least one first cure site monomer having at least one cure site, wherein tetrafluoroethylene is present in the first curable perfluoropolymer in an amount of at least about 50 mole percent; a second curable perfluoropolymer comprising tetrafluoroethylene, a second perfluoroalkylvinyl ether and at least one second cure site monomer having at least one cure site, wherein the second curable perfluoropolymer comprises fluoroplastic particles therein; and at least one curative.
