Polyplastics' DURAFIDE (R) PPS Delivers Increased Transmittance and Toughness in Laser-welded Applications
TOKYO, July 12, 2022 /Kyodo JBN-AsiaNet/ --

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 


Laser welding is a joining method that offers a long list of advantages, but it 
has been difficult to actually use with PPS due to its low laser transmittance 
and related mass production issues such as a narrow processing window. 
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 

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.
