PURPOSE:A flame-retardant resin composition improved in dripping and generation of organic gases on burning, by the incorporation of a specified quantity of zeolite powders into a polyolefin resin. CONSTITUTION:A resin composition obtained by incorporating 5-150pts.wt. powders of natural and/or synthetic zeolites (A) with an average particle diameter of 30mum or less, shown by the formula [where M is K, Na, Ca, Fe or Zn; a is the valence of the cation; X is 0.1-20; Y is 0-20 (the number of moles of water of crystallization)]; 0-30pts.wt. halogenated organic flame retardant and/ or halogenated organophosphorus flame retardant (B); and 0-15pts.wt. antimony and/or boron flame-retarding assistant (C) into 100pts.wt. olefin resin. Examples of the natural zeolites include chabazite and clinoptilolite, and examples of the synthetic zeolites include zeolite A and zeolite Z. |
