Laser transmission welding is also known as laser welding is a method employed for joining plastic parts. It enables even very small components with complex geometries to be produced in a cost-efficient and resource-friendly manner, making it part of the growing trend toward the miniaturization of electrical and electronic functions. This is why LANXESS has developed a wide range of laser-weldable polyamides and polybutylene terephthalates (PBT) Durethan LT and Pocan LT (Laser Transparency) and has recently expanded its range to include three new compounds. At K 2019, the international trade show for plastics and rubber taking place in Düsseldorf, the High-Performance Materials business unit will showcase these innovative compounds.
The new LANXESS material for laser welding is Pocan TP150-002. The 30%-glass-fiber-reinforced PBT compound is optimized for extremely high laser transparency. It exhibits a transmission of 13%, which is around double the transparency of most other laser-transparent PBT product types (measured with an LPKF TMG-3 at 980 nm and a test specimen thickness of 2 mm).
