PIN FR laser-weld PBT for electric vehicles
Sabic (pinfa member) has launched the world’s first laser-weldable flame retardant PBT compound. The performance glass fibre reinforced PBT (polybutylene terephthalate) compound can replace metal for demanding applications such as EVCUs (electric vehicle control units) which protect sensitive electronics from fire, smoke, impacts and moisture, and also for vehicle exterior parts, electrical and electronic components. The compound offers colorability, low warpage, electrical insulation, high dimensional stability, chemical resistance and fire resistance (UL 94 V-0 @ 1.5 mm). Because the compound offers high optical transmission (20% @ 3 mm) it can be bonded to absorptive materials by laser-welding, avoiding use of adhesives, chemicals, fasteners or vibration, so simplifying part design and accelerating manufacture throughput. The compound is an Edison Award winner for global innovation - Critical Safety Material Advancements (2025 silver).
