Abstract
A flame-retardant, wear-resistant resin composition includes a polymer composition and at least one metal hydroxide. The polymer composition consists of (a) at least one propylene-ethylene block copolymer, and (b) at least one polyolefin-rubber elastomer including polyolefin as a hard segment and rubber as a soft segment. The resin composition consists of 10 to 80% by weight of the component (a), and 20 to 90% by weight of the component (b). The metal hydroxide is present in the resin composition 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.
