is used. Melt index is 1, O
For larger flame retardants, there is a problem that the mechanical strength and elongation will decrease significantly when large amounts of non-halogenated flame retardants are mixed, and for those with an ethyl acrylate content of more than 20% by weight, even if they are highly cross-linked. However, the wear resistance is insufficient,
Also, if the product of melt index and ethyl acrylate content is outside the above range, either mechanical properties or abrasion resistance are insufficient.

As solid lubricants, waxes having good compatibility with ethylene-ethyl acrylate copolymer, such as polyethylene waxes and senkunro-type ester waxes with molecules of about 1 tl OOO to 3000, are preferable, but inorganic lubricants such as molybdenum disulfide are preferable. It's okay. The blending amount of the solid lubricant is 0 per 100 parts by weight of the ethylene-ethyl acrylate copolymer.
．． 1 to 10 parts by weight, especially 0.5 to 5 parts by weight.

の被覆材として頗る有用である。Wires that are wired inside electronic devices such as personal computers, electronic musical instruments, and microwave ovens, wires for vehicles, and wires for ships are wired or used in narrow and labyrinth-like areas inside the device. In many cases, the wires are subjected to intense training, and after wiring, they are heated and pose a risk of fire. On the other hand, the composition of the present invention has both good abrasion resistance and flame retardancy, so it is extremely useful as a coating material for electric wires such as internal wiring in devices, electric wires for vehicles, and electric wires for ships. .
