Polyplastics Offers Broad Slate of Engineering Thermoplastics for Laser Welding
TOKYO, Jan. 16, 2018 /Kyodo JBN-AsiaNet/ --

Polyplastics Co., Ltd. offers an extensive range of engineering thermoplastics 
which facilitate laser welding of housing components for the automotive and 
electrical/electronics industries. Materials such as DURACON(R) POM and 
DURANEX(R) PBT are highly compatible with laser welding and are finding broader 
end-use applications.


Laser welding is a bonding method that utilizes the laser transmissibility of a 
plastic material on one side (transmitting material) and another material 
containing additives such as carbon black that absorb laser light (absorbing 
material) on the other side. The wavelength of lasers, such as diode lasers or 
YAG lasers, is approximately 800-1,200nm which is slightly longer than the 
wavelength of visible light.

Polyplastics' slate of laser welding grades includes DURANEX PBT, a 
cost-balanced resin that exhibits excellent heat resistance, moldability, and 
electrical properties for housings. The company has optimized its DURANEX PBT 
family by re-examining the rubber content, together with its compounding 
agents, to develop DURANEX PBT 730LW which enables laser welding of workpieces 
as thick as 2mm which could not be achieved with a predecessor material. 

Another key product is DURACON POM which exhibits excellent light 
transmissibility, even when compared to other semi-crystalline engineering 
plastics. It also has a low melting point, allowing the laser output required 
for welding to be kept low, Polyplastics has released DURACON POM M90LP, which 
uses pigments that do not inhibit laser transmissibility. 

Polyplastics not only performs grade selection and development suitable for the 
laser welding method; it also offers CAE product design support and an 
evaluation system that utilizes an actual laser welding machine.
