Translucent laser weldable thermoplastic compositions and laser-welded products

摘要

The invention is directed to a thermoplastic resin composition comprising: ●from 10 to 80 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; ●from 1.5 to 40 weight percent of an amorphous high heat copolyester resin component that is produced by polymerizing a monomer mixture comprising a mixture of spiroglycol, ethylene glycol and terephthalic acid and or an ester thereof (SPG PET) and having a glass transition temperature (T_g) of 85 to 130° C.; and ●from 0.01 to 5 weight percent of an antioxidant, mold release agent, stabilizer, or a combination thereof.
