What can be welded?
In summary, all thermoplastics and almost any thermo-plastic elastomer, unfilled or filled can be welded.
For example, in current applications, polymers with a glass fibre percentage of up to 30% are laser welded.
Also different kind of polymers can be joined without problems - provided they are chemically compatible and the two melting temperature ranges overlap sufficiently.
Some examples of materials,
which can be welded:
PE, PP, PS, ABS, SAN, PA6, PA6.6, PC,
PMMA, PSU, PEEK, PET, PBT…
There is also a rule of thumb for natural
materials: What you can weld ultra-sonically
can also be laser welded… and many more.
Laserwelding of polymers is already
successfully used in numerous applications:
in the automotive, electronic and
telecommunication industries,
medical device technology, human care
and household devices.
