Abstract[English]
Thermoplastic compositions include: (a) from about 10 wt% to about 90 wt% of a polycarbonate component; (b) from about 2 wt% to about 40 wt% of a polycarbonate- siloxane (PC-Si) copolymer, wherein the PC-Si copolymer has a siloxane content of at least 25 wt%; (c) from about 2 wt% to about 15 wt% of a bisphenol A bis(diphenyl phosphate) (BPADP) flame retardant; and (d) from about 0.05 wt% to about 2 wt% of a polytetrafluoroethylene (PTFE) flame retardant. The combined weight percent value of all components does not exceed 100 wt%, and all weight percent values are based on the total weight of the composition.[French]
L'invention concerne des compositions thermoplastiques qui comprennent : (a) d'environ 10% en poids à environ 90% en poids d'un composant polycarbonate ; (b) d'environ 2% en poids à environ 40% en poids d'un copolymère polycarbonate-siloxane (PC-Si), le copolymère PC-Si ayant une teneur en siloxane d'au moins 25% en poids ; (c) d'environ 2% en poids à environ 15% en poids d'un retardateur de flamme de bisphénol A bis(diphényl phosphate) (BPADP) ; et (d) d'environ 0,05% en poids à environ 2% en poids d'un retardateur de flamme de polytétrafluoroéthylène (PTFE). La valeur de pourcentage en poids combinée de tous les composants ne dépasse pas 100 % en poids, et toutes les valeurs de pourcentage en poids sont basées sur le poids total de la composition.
