16 Claims

1. A thermoplastic composition comprising:

(a) from about 34.3 wt % to about 54.3 wt % poly(cyclohexylenedimethylene terephthalate) (PCT) or a copolymer thereof;

(b) at least 10 wt % of a reinforcing filler comprising glass fiber;

(c) from about 2 wt % to about 20 wt % of a laser direct structuring (LDS) additive comprising a tin oxide and an antimony oxide; and

(d) from about 5 wt % to about 50 wt % of a reflection additive comprising a titanium compound,

wherein the composition has a dissipation factor (Df) less than 0.01 as determined using an Agilent Split Post Dielectric Resonator at 1.1 gigahertz (GHz), and

wherein the combined weight percent value of all components does not exceed 100 wt %, and all weight percent values are based on the total weight of the composition.
