Abstract

Flame-resistant resin composition is prepared for use as a coating material and applied to electrical cables. The resin composition is not cross-linked, and contains no halogen. It is highly formable, flexible, heat-resistant and oil proof. The flame-resistant flexible resin composition includes 100 parts by weight of polymeric material including about 50 to 90 parts by weight of thermoplastic elastomer copolymer including polyolefin and rubber, about 5 to 25 parts by weight of a second copolymer including ethylene and vinyl-based compound containing at least one carbonyl group, and up to about 25 parts by weight of polyolefin having a crystallinity of at least about 55%, and about 30 to 200 parts by weight of at least one metal hydroxide a surface of which has not been treated with stearic acid.
