Abstract
The present disclosure relates to thermoplastic compositions. The disclosed compositions comprise a polycarbonate polymer, a polysiloxane-polycarbonate copolymer, a laser direct structuring additive, and a siloxane additive. Also disclosed are methods for making the disclosed thermoplastic compositions and articles of manufacture comprising the disclosed thermoplastic compositions.
Claims33
A thermoplastic composition comprising:
- a. a polycarbonate polymer;
- b. a polysiloxane-polycarbonate copolymer;
- c. a laser direct structuring additive;
- and
- d. a siloxane additive;
- wherein a molded article having a thickness of 3.2 mm formed from the composition exhibits a notched izod impact energy that is at least 10% greater than that exhibited by a molded article formed from an identical reference composition in the absence of the siloxane additive.
