PIN FRs for laser transmission plastic welding

pinfa member Lanxess has developed compounds with innovative non-halogenated flame-retardant packages, based on PBT (polybutylene terephthalates) and on polyamides, compatible with laser transmission welding. Laser welding is used to fuse small plastic parts, enabling complex geometries to be miniaturised, but requires laser transparency and specific processing characteristics. The new Lanxess materials also offer demanding performance characteristics: hydrolysis resistance (30% glass fibre reinforced PBT), UL94-V0 at 0.75 mm and comparative tracking index (CTI) of 600V (PA6) or very high laser transparency for thick-walled items (another 30% glass fibre PBT compound).
