Abstract[English]
Thermoplastic compositions include: (a) from about 35 wt% to about 65 wt% of a polycarbonate homopolymer component; (b) from about 0.1 wt% to about 30 wt% of a polybutylene terephthalate component; (c) from about 0.1 wt% to about 5 wt% of an aluminum hydroxide oxide component; and (d) from about 0.1 wt% to about 20 wt% of a flame retardant (FR) component. 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. The compositions have improved hydro-stability and low temperature impact properties.[French]
L'invention concerne des compositions thermoplastiques qui comprennent : (a) d'environ 35 % en poids à environ 65 % en poids d'un composant homopolymère polycarbonate ; (b) d'environ 0,1 % en poids à environ 30 % en poids d'un composant polytéréphtalate de butylène ; (c) d'environ 0,1 % en poids à environ 5 % en poids d'un composant oxyde d'hydroxyde d'aluminium ; et (d) d'environ 0,1 % en poids à environ 20 % en poids d'un composant ignifuge (FR). La valeur combinée de pourcentage en poids de tous les composants ne dépasse pas 100 % en poids, et toutes les valeurs de pourcentage en poids sont rapportées au poids total de la composition. Les compositions présentent des propriétés améliorées d'hydro-stabilité et de résistance aux chocs à basse température.
