Abstract: A thermoplastic composition includes: from about 29 wt % to about 49 wt % of a thermoplastic polymer component including a first thermoplastic polymer consisting of polybutylene terephthalate and a second thermoplastic polymer consisting of polycarbonate, polyethylene terephthalate, copolymers thereof, or a combination thereof; from about 1 wt % to about 30 wt % of a component comprising a polyester elastomer, an ethylene/alkyl acrylate/glycidyl methacrylate terpolymer compatibilizer, or a combination thereof; and from about 50 wt % to about 70 wt % of a ceramic fiber component including ceramic fibers. The first thermoplastic polymer is present the composition in a ratio of at least 2:1 as compared to the second thermoplastic polymer. Articles including the thermoplastic composition are also described.

Abstract: Thermoplastic compositions include: (a) from about 40 wt% to about 90 wt% of a polymer resin including poly(cyclohexylenedimethylene terephthalate) (PCT) or a copolymer thereof; (b) from about 20 wt% to about 50 wt% of a reinforcing filler including glass fiber; and (c) from about 1 wt% to about 20 wt% of an impact modifier comprising a di-block copolymer. The thermoplastic compositions are useful in consumer electronics (CE) articles, including a mobile phone or tablet, and specifically an antenna split for a mobile phone or tablet.

Abstract: Thermoplastic compositions include: (a) a thermoplastic polymer including a polycarbonate component; (b) a poly(carbonate-siloxane) copolymer; and (c) from 4 wt % to 25 wt % carbon black. The composition has a total siloxane content of from 2 wt % to 14 wt %. The thermoplastic compositions exhibit improved physical properties as compared to compositions that do not include the poly(carbonate-siloxane) copolymer, including volume resistivity, melt viscosity, impact strength, puncture impact energy and surface resistivity.
