Abstract:
A fluororubber-metal laminate sheet, which comprises a metallic sheet and a vulcanized fluorocarbon layer, provided on the metallic sheet by applying thereto a fluororubber composition comprising (A) 100 parts by weight of a polyol-vulcanizable fluororubber, (B) 10-50 parts by weight of amorphous graphite, (C) 1-15 parts by weight of a phenol resin, (D) 1-4 parts by weight of a silane coupling agent, (E) 0.5-8 parts by weight of a polyol-based vulcanizing agent, and (F) 0.5-6 parts by weight of a vulcanizing accelerator, followed by vulcanization of the fluororubber composition to form laminate, where the metallic sheet is free from either a chromating treatment or a chromating substitute treatment, is distinguished in characteristics such as sealability, compression resistance, air-heated aging resistance, anti-freezing liquid resistance, oil resistance, sticking resistance, abrasion resistance, etc.
