POLYPLASTICS OFFERS BROAD SLATE OF ENGINEERING THERMOPLASTICS FOR LASER WELDING

TOKYO, Jan 16 (Bernama) -- 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.
