Abstract
Provided is a process for fusion-bonding plastic parts with the aid of laser radiation of a wavelength outside the visible region, wherein a bonding region of a plastic part to be bonded comprises at least one material which is transparent in the visible region of the electromagnetic spectrum, is substantially colorless and absorbs the laser radiation, wherein the material comprises at least one nonionic compound that is resistant to the laser radiation, has a thermal stability of at least 300° C. and is selected from polycyclic organic compounds, doped tin oxides and hexaborides MBof lanthanides and alkaline earth metals M. Also provided is a preparation suitable for producing fusion-bonded plastic parts with the aid of laser radiation whose wavelength is outside the visible region, the preparation comprising: a thermoplastic matrix polymer suitable for forming the plastics parts; at least one of said material; optional UV stabilizers; and optional additives.
