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 resin, 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.
