Resinous composition having an increased flame retardance

摘要

A resinous composition having an increased flame retardance is disclosed, which comprises (A) 10 to 60% by weight of a mixture comprising 100 parts by weight of a polyolefin resin, 20 to 60 parts by weight of a halogenated organic flame-retardant agent, 7 to 30 parts by weight of antimony trioxide and 10 to 40 parts by weight of zinc borate hydrate, and (B) 90 to 40% by weight of a magnetic body powder. The compositions are endowed with surprising glowing combustion resistance as well as superior flame combustion resistance.
