Title:
LASER TRANSPARENT COMPOSITION AND MOLDED ARTICLES MADE THEREFROM
Document Type and Number:
WIPO Patent Application WO/2023/015542
Kind Code:
A1
Abstract:
Polyester polymer compositions are described containing one or more nucleating agents and optionally reinforcing fibers. The polyester polymer, for instance, can be polybutylene terephthalate. The polymer composition is particularly formulated in order to be substantially transparent at specific wavelengths of light. Consequently, the polyester polymer composition is well suited for use in laser transmission welding in which a laser beam passes through the polymer composition and forms a weld on an adjoining surface. In one aspect, a black pigment masterbatch can be added to the composition for further improving the transparency properties.
