Abstract[English]
Thermoplastic compositions include: (a) from about 10 wt% to about 85 wt% of a mechanically recycled polycarbonate; (b) from about 2 wt% to about 15 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 0.1 wt% to about 20 wt% of a flame retardant component; (d) from about 0.01 wt% to about 2 wt% of an anti-drip agent comprising polytetrafluoroethylene (PTFE); and (e) from greater than 0 wt% to about 10 wt% talc. 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 85 % en poids d'un polycarbonate recyclé mécaniquement ; (b) d'environ 2 % en poids à environ 15 % 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 0,1 % en poids à environ 20 % en poids d'un composant ignifuge ; (d) d'environ 0,01 % en poids à environ 2 % en poids d'un agent anti-goutte comprenant du polytétrafluoroéthylène (PTFE) ; et (e) de plus de 0 % en poids à environ 10 % en poids de talc. 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.
