MODIFIED INORGANIC FILLER

摘要

PROBLEM TO BE SOLVED: To provide a molded product of a fluorine-containing elastomer capable of withstanding the use at a high temperature of >=230 deg.C. SOLUTION: A modified inorganic filler is an inorganic filler (except a carbon filler) having <=0.5μm primary average particle diameter and is obtained by subjecting the inorganic filler to a treatment for reducing the surface activity thereof. A fluorine-containing elastomer composition for crosslinking comprises the fluorine-containing elastomer having crosslinkable groups and a crosslinking agent and/or a crosslinking promoter.
