Laser beam weldable thermoplastic molding materials

Thermoplastic molding materials containing at least two dyes, so that the material has a dark color (standard value Y = less than 30) with little or no transmission (not more than 10%) in the visible range (400-700 nm) at a layer thickness of 0.4-5 mm and a transmission of more than 10% in at least...

Beschreibung
Zusammenfassung:	Thermoplastic molding materials containing at least two dyes, so that the material has a dark color (standard value Y = less than 30) with little or no transmission (not more than 10%) in the visible range (400-700 nm) at a layer thickness of 0.4-5 mm and a transmission of more than 10% in at least some parts of the range 700-1200 nm when irradiated with laser light. Independent claims are also included for: (a) molded parts made of these materials; (b) composite molded parts bonded by laser transmission welding, in which at least one component consists of material as described above.
