Polyplastics Co., Ltd., a leading global supplier of engineering thermoplastics, is finding successful use of polyphenylene sulfide (PPS) in laser-welded applications such as automotive parts thanks to materials with enhanced capabilities. The company offers DURAFIDE (R) PPS which delivers greater transmittance and toughness and facilitates laser welding in a range of applications.

Polyplastics' linear-type DURAFIDE (R) PPS is characterized by its white natural color, as opposed to the reddish-brown natural color of competitive crosslink-type PPS materials. That gives it superior laser transmissibility (light transmissibility in the infrared region) and makes laser welding possible. DURAFIDE (R) PPS provides an approximately 6% improvement in laser transmittance which results in a wider processing window for a broad range of welding conditions. The material also delivers an approximately 28% improvement in toughness versus standard grades. This exceptional toughness is important for initial strength and durability. DURAFIDE (R) PPS also offers strong dimensional stability, low warpage, and chemical resistance. DURAFIDE (R) PPS enables the use of laser welding for production of automotive electric components for which this method could not readily be used before. These automotive parts include electric water pumps, shift actuators, electric variable valve-timing actuators, solenoid valves, and various sensors. Polyplastics is currently undertaking a development project to provide even better laser transmittance of PPS and further widen the processing window.
