USE OF A MIXTURE COMPRISING SPHERICAL METAL PARTICLES AND METAL FLAKES AS LASER-MARKING OR LASER-WELDABILITY AGENTS AND LASER MARKABLE AND/OR LASER WELDABLE PLASTIC

摘要

The invention relates to the use of a mixture comprising spherical metal particles and metal flakes as laser-marking or laser-weldability agents in a plastic, wherein the particle size distribution of the spherical metal particles and the metal flakes in the mixture determined by means of laser granulometry, in the form of the volume-averaged cumulative particle size distribution, have a Dmixture, 90- value of mixture,50 < 60 µm. The invention further relates to a master batch having a mixture comprising spherical metal particles and metal flakes. The invention furthermore relates to a laser-markable and/or laser-weldable plastic, having a mixture comprising spherical metal particles and metal flakes.
