あるため、糧々難燃化の検討が行われている。In general, the insulator for insulated wires is made of polyolefin copolymers, such as polyethylene, ethylene-vinyl acetate copolymer, which have excellent electrical properties, water resistance, cold resistance, strength, flexibility, and are easy to process. Something called fusion is widely used. However, since polyolefin copolymers are easily flammable, efforts are being made to make them flame retardant.

率、誘電正接が著しく悪化すると云う欠点があった。In this case, a method is generally adopted in which a polymer containing a halogen element such as chlorinated polyethylene or various halogen-containing organic compounds is mixed as a flame retardant. However, when polyolefin copolymers mixed with such flame retardants are cross-linked by irradiating radiation to improve heat resistance, hydrogen halides such as HCL are generated, which makes it difficult to remove moisture from electric wires. There is a drawback in that the dielectric constant and dielectric loss tangent of this isolated body deteriorate significantly when it is left in a hot atmosphere or in water.
