Abstract
Reinforced, flame-resistant thermoplastic composition consisting of: (A) a polymeric matrix consisting of an olefinic or styrene (co)polymer; (B) a quantity which is sufficient to give flame resistance properties, of an intumescent flame-retarding agent consisting of a mixture of (i) a compound containing nitrogen, insoluble in water, consisting of an oligomer or polymer of a derivative of 1,3,5-triazine and (ii) an ammonium phosphate, and (C) from 5 to 50% by weight with respect to the total composition of a phosphorite having a phosphorous content, expressed as BPL (Bone Phosphate of Lime) of more than 40% by weight.
