Abstract[English]
Thermoplastic compositions include: a) from about 30 wt% to about 60 wt% of at least one crystalline or semi-crystalline polymer; b) from about 5 wt% to about 20 wt% of at least one polycarbonate-siloxane copolymer; and c) from greater than 5 wt% to less than 25 wt% of a polyetherimide (PEI) polymer. 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 low warpage and good chemical resistance properties.[French]
Les compositions thermoplastiques comprennent : a) d'environ 30 % en poids à environ 60 % en poids d'au moins un polymère cristallin ou semi-cristallin ; b) d'environ 5 % en poids à environ 20 % en poids d'au moins un copolymère polycarbonate-siloxane ; et c) de plus de 5 % en poids à moins de 25 % en poids d'un polymère polyétherimide (PEI). 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. Les compositions présentent un faible gauchissement et de bonnes propriétés de résistance chimique.
