HEAT-RESISTANT FLAME-RETARDANT RUBBER COMPOSITION, INSULATED WIRE AND RUBBER TUBE

摘要

Provided are: a heat-resistant flame-retardant rubber composition which has low adhesiveness even in an uncrosslinked state; an insulated wire which has an insulating coating that is formed from this heat-resistant flame-retardant rubber composition; and a rubber tube which is formed from this heat-resistant flame-retardant rubber composition. A heat-resistant flame-retardant rubber composition which is obtained by blending 10-100 parts by mass of an inorganic filler per 100 parts by mass of a mixture that is obtained by mixing (A) a vinylidene fluoride-hexafluoropropylene copolymer rubber and/or a vinylidene fluoride-hexafluoropropylene-tetrafluoroethylene copolymer rubber and (B) a polyvinylidene fluoride at a ratio of from 90:10 to 60:40 (mass ratio); an insulated wire which has an insulating coating that is formed from this rubber composition by irradiation of ionizing radiation; and a rubber tube which is formed from this heat-resistant flame-retardant rubber composition by irradiation of ionizing radiation.
