Abstract
Abstract A flame retardant polyolefin resin composition which, when molded, affords a molded product having highly flame retardant properties, no dripping properties, a smooth surface and an excellent appearance and superior resistances to heavy metal deterioration, heat deterioration and weather is provided, which composition consists of (A) 5 - 60% by weight of a halogen-containing flame retardant, (B) 100 - 10% by weight of antimony trioxide based on the weight of the halogen-containing flame retardant, (C) 0.5 - 15% by weight of a crosslinking agent, (D) 0.05 - 5% by weight of a specified thiophosphite, and (E) the balance % by weight of a polyolefin raein, the total of the quantities of (A), (B), (C), (D) and (E) being 100% by weight. If necessary, a processing aid may be further added to the above flame retardant polyolefin resin composition.
