Abstract: The disclosure concerns methods for molding a polycarbonate containing plastic, the method including: (a) injecting a composition into a mold, the composition including (i) about 49 wt % to about 97.9 wt % of polycarbonate, (ii) about 2.0 wt % to about 50 wt % of a polycarbonate-polysiloxane copolymer, and (iii) about 0 wt % to about 1.0 wt % of at least one release agent; and (b) releasing the composition from the mold. The mold includes at least one draft angle of about 0.1 degrees to about 7 degrees. The polycarbonate blend includes a melt flow volume rate (MVR) of at least about 25 cm3/10 min as measured according to ISO 1133 at 300° C. and 1.2 kg.

Abstract: Automotive articles include a polycarbonate-siloxane copolymer including: from about 49.5 wt % to about 97.95 wt % of at least one polycarbonate polymer; from about 2.0 wt % to about 49.5 wt % of at least one polycarbonate-siloxane copolymer; and from about 0.05 wt % to about 1.0 wt % of at least one release agent. The composition exhibits a melt volume flow rate of at least about 25 cm3/10 min, a ductile/brittle transition temperature of less than or equal to 10° C., and high gloss after metallization. Methods of forming an article include: forming a thermoplastic composition, and injection molding, extruding, rotational molding, blow molding or thermoforming the thermoplastic composition in a mold to form the article. Such compositions and methods may be used to form articles including, but not limited to, automotive bezels and reflectors.

Abstract: The present disclosure relates to articles formed from polycarbonate prepared according to a melt polymerization method wherein. An article prepared by a process comprising the steps of: forming a polycarbonate resin via melt transesterification; mixing a flame retardant component to form a composition, wherein the mixing is accomplished as an online operation; and forming the article from the composition, wherein the article achieves a better flame rating than a comparative article formed from a substantially identical reference composition comprising the same loading of the polycarbonate resin and the flame retardant component, but a mixing of the polycarbonate resin and the flame retardant component of the substantially identical reference composition is accomplished as an offline operation.
