A flame-retardant, wear-resistant resin composition, useful for electrical insulation

摘要

A flame-retardant, wear-resistant resin composition comprises a polymer composition and at least one metal hydroxide. The polymer composition consists of components (a) and (b) which are (a) at least one propylene-ethylene block copolymer, and (b) at least one polyolefin-rubber elastomer containing polyolefin as a hard segment and rubber as a soft segment. The component (a) is 10 to 80% by weight, and component (b) is 20 to 90% by weight. The metal hydroxide is in an amount in the range of 30 to 300 parts by weight per 100 parts by weight of the polymer composition. A good balance of properties can be obtained.
