Abstract

An insulation composition and an electric wire are provided which can have high flame retardance even containing components besides ethylene-ethylacrylate copolymer. The composition includes 100 partsby mass of a resin component, 2 parts by mass or more and 20 parts by mass or less of zinc tin oxide, and 0.3 parts by mass or more and 15 parts by mass or less of a bromine flame retardant. A resincomponent includes a first component including a copolymer of tetrafluoroethylene and alfa-olefin with the carbon number of 2 or more and 4 or less, and a second component including ethylene-ethylacrylate copolymer. Mass proportion of the first component in the resin component is 70 percent by mass or more and 98 percent by mass or less. Mass proportion of the second component in the resin component is 2 percent by mass or more and 30 percent by mass or less.

Description

technical field [0001] The present invention relates to insulating compositions and electric wires. Background technique [0002] The coating of electric wires requires high heat resistance and flame retardancy. A tetrafluoroethylene-propylene copolymer is known as a material for the coating layer (see Patent Document 1). Tetrafluoroethylene-propylene copolymers are expensive. Therefore, it is known to use a mixed material of a tetrafluoroethylene-propylene copolymer and a low-priced polyolefin or the like as a material for the coating layer. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2-245047 Contents of the invention [0006] The problem to be solved by the invention [0007] However, blended materials of tetrafluoroethylene-propylene copolymers and low-priced polyolefins generally have low flame retardancy. Here, according to one aspect of the present invention, an object thereof i...
