Abstract: The invention relates to an exterior panel assembly for a vehicle, the assembly comprising a sheet having side edges, a first and second surface opposite of each other, and comprising a thermoplastic material, wherein the sheet is transparent to electromagnetic radiation in at least one of the ranges for radio waves, infrared radiation, visible light and ultraviolet radiation; a heating device comprising an infrared emitter for emitting infrared rays towards the sheet; and a housing structure for accommodating the heating device, wherein the housing structure opens up towards the sheet with an opening, and wherein the sheet extends over the opening of the housing structure. The inventor further relates to a vehicle comprising such an exterior panel assembly.

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: Thermoplastic housings include a polycarbonate-siloxane copolymer comprising: 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 housing 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 a substantial tensile yield strength retention improvement when exposed to sunscreen. Methods of forming a housing include: forming the thermoplastic composition; and injection molding, extruding, rotational molding, blow molding or thermoforming the thermoplastic composition in a mold to form the housing. Such compositions and methods may be used to form articles including, but not limited to housings for consumer devices.
