Abstract
A thermoplastic composition includes: (a) poly(cyclohexylenedimethylene terephthalate) (PCT) or a copolymer thereof; (b) at least 10 wt % of a reinforcing filler comprising glass fiber; (c) a laser direct structuring (LDS) additive comprising a tin oxide, an antimony oxide, or a combination thereof; and (d) a reflection additive comprising a titanium compound. A weight ratio of total titanium in the composition to the LDS additive in the composition is at least 0.7:1, or a weight ratio of total titanium in the composition to the PCT is 1.1:1 or less.
Claims16
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.
