- Amorphous thermoplastics
- Semicrystalline thermoplastics
Assuming that there are no additives, amorphous thermoplastics are transparent within the visual range. By contrast, semicrystalline thermoplastics appear opaque to milky to the human eye. In principle, thermoplastics of the same type can be welded together using a laser. Nevertheless, attention must be paid to the optical properties.
The table below lists the material combinations that can be laser welded. In addition to these combinations, the range can also be expanded by using modified blends.
