More Information
Summary:A laser weldable composition made from a process of melt blending a combination of a partially crystalline thermoplastic polyester component such as poly(butylene terephthalate), an amorphous thermoplastic polycarbonate having a Fries rearrangement of greater than 150 to 10,000 ppm, and a filler such as glass fiber. The laser weldable composition has a polycarbonate aryl hydroxy end-group content of at least 300 ppm and provides improved near infrared transmission at 960 nanometers. A method welding components made from the weldable composition and welded articles made therefrom are also disclosed.
