ABSTRACT:
A flame-retardant composition is prepared by mixing 100 parts by weight of a rubber or plastics free from any halogen with about 50 to about 200 parts by weight of magnesium hydroxide having an average particle diameter of about 0.3 to about 2 .mu.m and about 5 to about 50 parts by weight of carbon black powder having an oil absorption of about 0.5 to about 2.0 ml/g, and then cross-linking the mixture with an organic peroxide, sulfur, or a sulfur compound as a vulcanizing agent. By forming an electrical insulation and/or a sheath of the flame-retardant composition, there is provided a flame-retardant cable of the type including a cable core composed of an electric conductor coated with the electrical insulation or a plurality of such cores twisted together and covered, together with a filler, with the sheath. The flame-retardant composition and the flame-retardant cable using this composition possess high flame resistance while possessing acceptable mechanical properties and will not evolve any hydrogen halide or other noxious gas if burnt. With less smoke emission than conventional cables on fire, the composition and the cable are less hazardous.
