Abstract[English]
Thermoplastic compositions include: a. from about 10 wt% to about 85 wt% of a polycarbonate component; b. from greater than 10 wt% to about 50 wt% of a polyester component; and c. from about 5 wt% to about 40 wt% of a polycarbonate-siloxane copolymer having a siloxane content of from 25 wt% to 60 wt%. The polycarbonate component in a. is different from the polycarbonate-siloxane copolymer in c. The composition comprises less than 1.0 wt% of a styrene-acrylonitrile encapsulated polytetrafluoroethylene (TSAN). In certain aspects the composition is fluorine-free. 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]
Les compositions thermoplastiques selon l'invention comprennent : a. d'environ 10% en poids à environ 85% en poids d'un composant polycarbonate; b. de plus de 10% en poids à environ 50% en poids d'un composant polyester; et c. d'environ 5% en poids à environ 40% en poids d'un copolymère polycarbonate-siloxane ayant une teneur en siloxane de 25% en poids à 60% en poids. Le composant polycarbonate en a. est différent du copolymère polycarbonate-siloxane en c. La composition comprend moins de 1,0% en poids d'un polytétrafluoroéthylène encapsulé par un polymère styrène-acrylonitrile (TSAN). Dans certains aspects, la composition est exempte de fluor. La valeur des pourcentages en poids combinés 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.
