Abstract[English]
Thermoplastic compositions include: a. from about 10 wt% to about 90 wt% of a polycarbonate homopolymer component; b. from about 1 wt% to about 90 wt% of a polycarbonate copolymer component; c. from about 1 wt% to about 15 wt% of a flame retardant component including a spirocyclophosphazene flame retardant additive; and d. from about 0.05 wt% to about 15 wt% of at least one additional additive. The compositions have improved UL94 flame retardant ratings and high heat distortion temperature (HDT) properties.[French]
L'invention concerne des compositions thermoplastiques comprenant : a. d'environ 10 % en poids à environ 90 % en poids d'un composant homopolymère de polycarbonate ; b. d'environ 1 % en poids à environ 90 % en poids d'un composant copolymère de polycarbonate ; c. d'environ 1 % en poids à environ 15 % en poids d'un composant ignifuge comprenant un additif ignifuge à base de spirocyclophosphazène ; et d. d'environ 0,05 % en poids à environ 15 % en poids d'au moins un additif supplémentaire. Les compositions présentent un indice d'inflammabilité UL94 amélioré et des propriétés de température de fléchissement sous charge (TFC) élevées.
