摘要:
As a polymer composition for electrical wire coating is provided a vinylidene fluoride polymer composition, which has such heat-resistance as to withstand the heat generated from a wire in service and exhibits satisfactory flexibility even after the change with the passage of time. The polymer composition for electrical wire coating comprises a vinylidene fluoride copolymer and a vinylidene fluoride homopolymer. The preferable compounding ratio in the polymer composition is in the range of 20 to 80% by weight of a vinylidene fluoride copolymer and 80 to 20% by weight of a vinylidene fluoride homopolymer. The vinylidene fluoride copolymer is preferably one comprising 95 to 70% by weight of vinylidene fluoride and 5 to 30% by weight of a monomer copolymerizable with vinylidene fluoride.
