Abstract
A fluoroelastomer composition is disclosed, which comprises a mixture of 100 parts by weight of a tetrafluoroethyline-propylene copolymer, not smaller than 1 part by weight and smaller than 100 parts by weight of a vinylidene fluoride-fluoroolefin copolymer having a fluoroolefin content of 1 to 20 mol %, and a cross-linking agent, said mixture being cross-linked by irradiation with electron beams. The fluoroelastomer composition has a high mechanical strength and improved low temperature characteristics. When the content of the vinylidene fluoride-fluoroolefin copolymer is not smaller than 10 parts by weight and smaller than 100 parts by weight per 100 parts by weight of the tetrafluoroethylene-propylene copolymer the fluoroelastomer composition is suitable as a material for producing heat shrinkable tubes.
