Selection Guide

Should I choose a laser marking additive: powder, masterbatch, or pre-dispersion?

In a practical review of laser marking powder, masterbatch, and pre-dispersion comparisons, comparing product names or supplier representative figures alone is not sufficient. First, the required functions of the final part or film, acceptable appearance and processing range, and actual test conditions must be defined. Then, candidate materials must be compared under the same base material, thickness, process, and conditioning conditions to obtain meaningful conclusions.
