Photothermal Conversion and Local Heat Generation in Laser-Marking Additives

Laser-marking additives alter where and how incident optical energy is absorbed, scattered, converted, and conducted; the resulting temperature-time-volume response depends on wavelength, pulse and scan conditions, dispersion, polymer thermal chemistry, geometry, and heat loss, so optical absorption alone does not prove mark contrast or safe processing.

Dispersing Laser-Active Pigments Without Agglomerates or Visible Specking

Reliable laser-marking compounds require separate control of wetting, deagglomeration, stabilization, distribution, melt processing, contamination, and final-part transfer; visible specks must be identified as pigment clusters, contaminants, voids, unmelt, degradation, or surface defects before the dispersion route is changed.
