Abstract
Described herein is a curable fluoropolymer composition comprising: an amorphous fluoropolymer; and particles of a metal fluoride, wherein the particles are not substantially surface treated and wherein the metal of the metal fluoride comprises at least one of an alkaline earth metal, a Group III transition metals, and a Lanthanide metals. Also described are cured articles made with the curable fluoropolymer composition.
Claims20
A curable fluoropolymer composition comprising:
- an amorphous fluoropolymer, wherein the amorphous fluoropolymer comprises at least one of an iodine-, a bromine- and a nitrogen-containing cure site group;
- and
- particles of a metal fluoride, wherein the particles comprise less than 10% by weight of organic moieties on the particles' surface and wherein the metal of the metal fluoride comprises at least one of an alkaline earth metal, a Group III transition metals, and a Lanthanide metals.
A cured article comprising:
- a fluoroelastomer, wherein the fluoroelastomer comprises at least one of an iodine-, a bromine- and a nitrogen-containing cure site group;
- and
- particles of a metal fluoride, wherein the particles comprise less than 10% by weight of organic moieties on the particles' surface and wherein the metal of the metal fluoride comprises at least one of an alkaline earth metal, a Group III transition metal particles, and a Lanthanide.
