Title (EN) FLAME RETARDANT POLYMERIC COMPOSITIONS
(FR) COMPOSITIONS POLYMÈRES IGNIFUGES
Abstract: front page image
(EN)The present invention provides flame retardant thermoplastic moulding compositions comprising: A) from 65% to 99,5% by weight (with respect of the total weight of the final 5 composition) of a polyolefinic polymer particularly selected among polypropylene polymers; B) from 0,1% to 30% by weight (with respect of the total weight of the final composition) of a synergic mixture of an hypophosphorous acid metal salt and halogenated organic compounds ; io C) from 0,5% to 10 % by weight (with respect of the total weight of the final composition) of a plurality of selected additives consisting of processing aids, heat and process stabilisers, UV stabilisers, antidripping agents (PTFE -Polytetrafluoroethylene), pigments, mould releasing agents, nucleating agents is D) from 0% to 50% by weight (with respect of the total weight of the final composition) of an inorganic filler. The total of the percentages by weight of components A to D is 100 %.
(FR)La présente invention fournit des compositions de moulages thermoplastiques ignifuges comprenant : A) de 65 % à 99,5 % en poids (par rapport au poids total de la composition finale) d'un polymère polyoléfinique particulièrement choisi parmi des polymères de type polypropylène ; B) de 0,1 % à 30 % en poids (par rapport au poids total de la composition finale) d'un mélange synergique d'un sel métallique d’acide hypophosphoreux et de composés organiques halogénés ; C) de 0,5 % à 10 % en poids (par rapport au poids total de la composition finale) d'une pluralité d'additifs choisis parmi des adjuvants de fabrication, des stabilisateurs thermiques et de transformation, des absorbeurs de rayons UV, des agents anti-égouttement (le PTFE à savoir le polytétrafluoroéthylène), des pigments, des agents de démoulage, des agents de nucléation ; et D) de 0 % à 50 % en poids (par rapport au poids total de la composition finale) d'une charge inorganique. Le total des pourcentages en poids des composants A à D représente 100 %.
