PCT No. PCT/JP93/00550 Sec. 371 Date Aug. 6, 1993 Sec. 102(e) Date Aug. 6, 1993 PCT Filed Apr. 27, 1993 PCT Pub. No. WO93/23469 PCT Pub. Date Nov. 25, 1993.A fluorine-containing elastomer composition consists essentially of (A) a peroxide-vulcanizable fluorine-containing elastomer containing iodine and/or bromine which becomes a vulcanizing point, (B) an organic peroxide, (C) a co-vulcanizing agent and (D) a hydrotalcite compound or a calcined product thereof. The composition of the present invention is markedly improved in permanent compression set and adhesion after vulcanization while maintaining excellent tensile characteristics, heat resistance and chemical resistance corresponding to those of conventionally known peroxide-vulcanizable fluorine-containing elastomer, and therefore is suitable for the uses such as an O-ring, a gasket and an oil seal. |
