Title (EN) THERMOPLASTIC POLYCARBONATE COMPOSITIONS
(FR) FORMULES DE POLYCARBONATES THERMOPLASTIQUES
Abstract:
(EN) Disclosed herein is a thermoplastic composition comprising: a polycarbonate; an impact modifier; a polycarbonate-polysiloxane copolymer; a poly(arylene ether)-polysiloxane copolymer; and an organophosphate in an amount of 2 to 20 weight percent based on the combined weight of polycarbonate, impact modifier, polycarbonate-polysiloxane copolymer, and poly(arylene ether)-polysiloxane copolymer, wherein the composition has a notched Izod impact strength of greater than or equal to 4 kilojoules per square meter (kJ/m2) as determined according to ISO 180/A, a melt viscosity rate of less than or equal to 130 Pascal seconds (Pa.s) as determined according to ISO11443 at 1500 s-1 and 280°C, and a UL94 rating of V1 or better at 0.8 millimeter thickness.
(FR) La présente invention concerne une composition thermoplastique comprenant : un polycarbonate ; un modificateur d'impact ; un copolymère polycarbonate-polysiloxane ; un copolymère poly(arylène éther)-polysiloxane ; et un organophosphate à une teneur comprise entre 2 et 20 % massiques par rapport à la somme des masses du polycarbonate, du modificateur d'impact, du copolymère polycarbonate-polysiloxane et du copolymère poly(arylène éther)-polysiloxane, la composition présentant une résistance à l'impact Izod à encoche supérieure ou égale à 4 kilojoules par mètre carré (kJ/m2) comme déterminé selon ISO 180/A, un taux de viscosité à l'état fondu inférieur ou égal à 130 pascals seconde (Pa.s) comme déterminé selon ISO11443 à 1500 s-1 et 280 °C, et un score UL94 supérieur ou égal à V1 à une épaisseur de 0,8 millimètre.
