Foamed polycarbonate articles with improved impact and methods of making and uses thereof

본 발명은 개선된 다축 충격 강도를 나타내는 발포 열가소성 조성물에 관한 것이다. 발포 열가소성 조성물은 충격 강도 및 화염 성능을 요구하는 다수의 것에 이용될 수 있다. A foamed article includes from about 80 wt. % to about 95 wt. % of a polycarbonate base resin including a first polycarbonate and a second polycarbonate, from about 3 wt. % to about 16 wt. % of a polysiloxane-polycarbonate copolymer, from about 0.01 wt. % to about 1 wt. % of a non-bromine flame retardant, from about 0.1 wt. % to about 10 wt. % of filler, and from about 0.01 wt. % to about 1 wt. % of a mold release agent. The foamed article exhibits a V0 rating at 3 mm measured according to UL 94. The foamed article exhibits improved multi-axial impact strength and can be employed in applications requiring impact strength and flame performance.
