THERMOPLASTIC COMPOSITIONS AND SHAPED ARTICLES THEREOF
A thermoplastic composition comprising: a homopolycarbonate; a poly(carbonate siloxane) component present in an amount effective to provide 0.5-20 wt % total siloxane content; an antimicrobial agent comprising silver zirconium phosphate, silver phosphate glass, or a combination thereof; optionally, an additive composition; each based on the total weight of the composition which totals to 100 wt %.
MULTILAYER COMPOSITE WITH THERMAL BARRIER PROPERTIES
The present disclosure relates to a multilayer composite that may include a multilayer composite that may include a first barrier layer and a first foam layer. The first foam layer may include a silicone-based matrix component, a flame retardant filler component, and an insulation filler component. The multilayer component may have a thickness of at least about 0.5 mm and no greater than about 10 mm. The multilayer component may also have a HBF flammability rating as measured according to ASTM D4986.

Polysiloxanes in thermoplastic elastomer compounds for overmolded thermoplastic articles
An overmolded thermoplastic article includes a substrate portion molded from a thermoplastic resin compound and an overmold portion molded from a thermoplastic elastomer compound. The thermoplastic resin compound includes thermoplastic polymer resin. The thermoplastic elastomer compound includes thermoplastic elastomer and polysiloxane as a mold release agent, and is free of wax. The overmold portion is bonded onto the substrate portion with a peel strength at least comparable to that of an overmolded thermoplastic elastomer compound containing wax as a mold release agent instead of the polysiloxane. Undesirable effects observed with the use of wax as a mold release agent in overmolded thermoplastic elastomer compounds such as blooming and ease of scratching/marring can be reduced, while desirable properties such as silky feel of the surface of the overmold portion and good bonding of the overmold portion onto the substrate portion can be at least maintained.
