Patent number: 7695815Abstract: A laminate contains a first layer and a second layer. The first layer contains a first composition that contains polycarbonate, polycarbonate-polysiloxane copolymer, impact modifier and polyetherimide, wherein the polycarbonate constitutes at least about 50% by weight of the composition and a 3.2 millimeter thick, 7.6 centimeter square sample of the first composition produces a smoke density (Ds) of less than 275 after a 4-minute burn, measured according to ASTM E 662-03. The first composition may contain about 50 wt. % to about 97 wt. % polycarbonate, about 0.5 wt. % to about 25 wt. % polycarbonate-polysiloxane copolymer, about 0.5 wt. % to about 20 wt. % impact modifier, and about 2 wt. % to about 15 wt. % polyetherimide, by weight. An article may contain a sheet or film made from such a composition. A laminate or article may be made to include a first layer or sheet that includes such a composition.Type: GrantFiled: December 22, 2005Date of Patent: April 13, 2010Assignee: Sabic Innovative Plastics IP B.V.Inventors: Naveen Agarwal, Thomas Ebeling, Srinivas Siripurapu
