Abstract[English]
A polycarbonate composition including a linear homopolycarbonate; a branched polycarbonate; a non-fluorinated flame retardant comprising an organophosphorus flame retardant comprising a phosphorus-nitrogen bond, a poly(carbonate-siloxane) comprising greater than 10 wt% to less than or equal to 30 wt% siloxane repeating units, based on the total weight of the poly(carbonate-siloxane), a colorant composition comprising greater than 4 wt% of titanium dioxide; and optionally, an additive composition; wherein the linear homopolycarbonate, the branched polycarbonate, the non-fluorinated flame retardant, the poly(carbonate-siloxane), the colorant composition, and the optional additive composition total 100 wt%; and wherein a sample of the composition has a UL-94 flammability test rating of V-0 at a thickness of 1.5 mm or thinner.[French]
L'invention concerne une composition de polycarbonate comprenant un homopolycarbonate linéaire ; un polycarbonate ramifié ; un retardateur de flammes non fluoré comprenant un retardateur de flamme organophosphoré comprenant une liaison phosphore-azote, un poly (carbonate-siloxane) comprenant plus de 10 % en poids à moins de 30 % en poids de motifs de répétition siloxane, sur la base du poids total du poly (carbonate-siloxane), une composition de colorant comprenant plus de 4 % en poids de dioxyde de titane ; et éventuellement, une composition d'additif ; l'homopolycarbonate linéaire, le polycarbonate ramifié, le retardateur de flammes non fluoré, le poly (carbonate-siloxane), la composition de colorant et la composition d'additif facultative au total de 100 % en poids ; et un échantillon de la composition ayant un indice de test d'inflammabilité UL-94 de V-0 à une épaisseur de 1,5 mm ou plus mince.
