FLUORINATED ELASTOMER COMPOSITION AND METHOD FOR PRODUCING SAME, MOLDED ARTICLE, CROSSLINKED MATERIAL, AND COATED ELECTRIC WIRE

摘要

To provide a fluorinated elastomer composition which is excellent in heat discoloration resistance and moldability, and a molded product, cross-linked product and covered electric wire, using such a fluorinated elastomer composition. A fluorinated elastomer composition comprising a fluorinated rubber (a) and a fluorinated copolymer (b), wherein the fluorinated copolymer (b) has units (A) derived from tetrafluoroethylene and units (B) derived from ethylene in a molar ratio [(A)/(B)] of the units (A) to the units (B) of from 25/75 to 80/20; the fluorinated copolymer (b) has a crystallization temperature of from 100 to 210°C and a melt flow rate of from 0.1 to 1,000 g/10 min.; and the mass ratio [(a)/(b)] of the fluorinated rubber (a) to the fluorinated copolymer (b) is from 80/20 to 20/80.
