Translucent laser weldable thermoplastic compositions and laser-welded products

A laser welded, molded article comprising a first laser-transmissive article welded to a second laser-absorbing article, wherein the first part comprises a product consisting of:

• a. from 10 to 60 weight percent of a partially crystalline polyester component selected from the group consisting of terephthalate-derived polyesters, naphthalate-derived polyesters, succinate-derived polyesters, and furanoate-derived polyesters;
• or combinations thereof;
• b. from 10-50 weight percent amorphous polycarbonate;
• c. from 5 to 50 weight percent of a filler;
• d. from 0.01 to 5 weight percent of an antioxidant, mold release agent, stabilizer, or a combination thereof;
• e. from 1.5 to 40 weight percent of copolyester prepared by melt polymerization, amorphous polyester produced by polycondensation of a monomer mixture comprising of diol component containing spiroglycol and ethylene glycol (in a molar ratio of 45 to 55, respectively) and dicarboxylic acid component containing terephthalic acid and/or an ester thereof (SPG PET) terephthalic acid and/or an ester thereof (SPG PET);
• and
• wherein the composition when molded into an article having a 2.0 mm thickness, offers a NIR transmission at 980 nm of greater than 57%.
