Abstract

PURPOSE:To obtain a composition having well-balanced extrusion moldability and vulcanization properties, by compounding a specific fluororubber with rice bran wax. CONSTITUTION:The objective composition is produced by compounding (A) a fluororubber copolymer composed of a vinylidene fluoride unit and a hexafluoropropylene unit or a fluororubber terpolymer composed of the above two units and a tetrafluoroethylene unit and having an intrinsic viscosity [eta]of 70-90ml/g (in methyl ethyl ketone at 35 deg.C), an Mw/Mn ratio of 2-5 (Mw is weight-average mol. wt.; Mn is number-average mol. wt.) and a ratio M5/[eta] of 0.1-0.3 [M5 is fraction (%) of polymer having a mol. wt. of <=50,000 in the fluororubber] with (B) 0.1-5pts.wt. of a rice bran wax based on 100pts.wt. of the fluororubber and (C) an additive to form a vulcanized elastomer.
