Ultradur® LUX – PBT with outstanding transparency for laser welding

Ultradur® LUX is a PBT that offers new possibilities for joining plastics using laser transmission welding. The thermoplastic shows a previously unachieved laser transparency in the range of 900 to 1100 nm – at a consistently high level. The reason for this is that with this PBT the laser beam is considerably less scattered and much less widened. At the welding laser wavelengths, Ultradur® LUX thus lets through much more light than standard PBT.

The properties of this plastic give the processor using laser welding as a connecting method a number of advantages:

  • Greater freedom of design
  • Very wide process window
  • Shorter cycle times
  • High process consistency
  • High quality consistency
  • Greater flexibility
