Laser marking additives can change the spectral absorption characteristics of plastics, especially for the special plastics which do not absorb laser, the correct use of laser marking additives can be suitable for laser marking, and the quality can be comparable to that of normal marking.
1. The main function of laser marking additive is to absorb laser energy, convert laser beam into heat energy, and produce heating, carbonization, evaporation and chemical reaction on plastics.
2. There are many kinds of additives for different lasers. For example, additives for carbon dioxide laser marking, for plastics with different chemical properties, there are different varieties of light laser marks on dark background and dark laser marks on light color background. Laser marking additive is a kind of additive specially designed for YAG plastic laser marking machine. It is suitable for PE, PP, GPPS, hips, ABS, pet, PBT, nylon, epoxy resin, ABS / PC, PC.
