Carbon black (CB)/polypropylene (PP) compounds were marked using a 532 nm Nd:YAG laser. Generally, the presence of a small amount of CB in PP led to a dramatic decrease in ablation threshold. Both thermophysical and photochemical reactions were found cooperative during laser processing of conventional polymers. Discoloration was basically the mechanism operative during laser marking polymer compounds.
