Abstract:
1. A fluorine-containing crosslinkable elastomer composition comprising a fluorine-containing crosslinkable elastomer other than a fluorosilicone rubber and a filler, in which when the filler is heated at 200° C. for two hours, a weight reduction ratio per unit surface area of the filler is not more than 2.5×10 −5 % by weight/m 2 and when the filler is heated at 200° C. for 15 minutes, a total amount of organic gas generated from the filler is not more than 2.5 ppm; said filler is subjected to treatment for making its surface hydrophobic and then heat-treated to remove volatile components prior to blending with the fluorine-containing crosslinkable elastomer.
