Abstract:
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.

US Patent:
7799855, Sep 21, 2010
Filed:
Oct 4, 2004
Appl. No.:
10/957799
Inventors:
Thomas Ebeling - Evansville IN, US
Monica Martinez Marugán - Bergen op Zoom, NL
Srinivas Siripurapu - Evansville IN, US
Assignee:
Sabic Innovative Plastics IP B.V.
International Classification:
C08K 5/523
US Classification:
524127, 524140, 524141
Abstract:
A thermoplastic composition contains about 20 to about 90 wt. % of a polycarbonate resin; up to about 35 wt. % of an impact modifier; about 0. 5 to about 30 wt. % of a polysiloxane-polycarbonate copolymer; and about 0. 5 to about 20 wt. % of a phosphorus-containing flame retardant, each based on the total combined weight of the thermoplastic composition, exclusive of any filler. An article of manufacture having a wall having a thickness of 3 mm or less may be made using the composition, e. g. , by molding, extruding, or shaping the above-described composition into an article. Alternatively, an article may be made by ultrasonically welding a first part comprising the foregoing composition a second part.
