PURPOSE:To obtain the subject molding useful for a sealing material, etc., having excellent heat resistance, durability and sealing property by crosslinking a rubber composition comprising a specific ratio of fluorocarbon rubber and nitrile rubber with a peroxide crosslinking agent. CONSTITUTION:65-99.99 pts.wt., preferably 70-95 pts.wt. fluorocarbon rubber such as copolymerized rubber of vinylidene fluoride and hexafluoropropylene is mixed with 35-0.01 pts.wt., preferably 30-5 pts.wt. nitrile rubber such as a copolymer of acrylonitrile and butadiene and the resultant rubber composition is crosslinked with a peroxide crosslinking agent such as dicumyl peroxide to afford the aimed molding. |
