Laser Marking Additives for Plastic Compounds

Iriotec® 8825 by Susonity is a color neutral laser marking pigment. For polymers that already show a slight reaction with the laser, it will enhance the effect and make laser marking an economic and reliable marking process. It is composed of mica (46-62%) and (Sn/Sb)O₂ (38-54%).

• Most transparent solution for laser marking in polymers, additional applications are laser welding, laser direct structuring for whitish to light colored formulations.
• It is compatible with polyolefins (PE, PP) and aromatic polymers (PC, ABS, SAN, PBT) for dark markings, in aliphatic polymers (PMMA, POM, PA) for bright markings even for fluoropolymers.
• It is suitable for transparent, light and dark colors marking.
• In strongly hiding formulations, 0.5% is suggested for optimum performance.
• Recommended dosage of Iriotec® 8825 in transparent applications should be >0.1%.

EXPLAZ™ HT-34D by Milliken is an optimized laser marking additive for polyamides. Provides a high-contrast marking at low loadings in engineering polymers. It combines fast laser response with controlled impact on appearance, facilitating reliable identification across demanding applications.

• It is designed for injection molding processing.
• Offers flexibility, good heat resistance and weatherability.
• It is compatible with IR & UV laser systems and has dark or light marking capability.
• EXPLAZ™ HT-34D is suitable for demanding applications such as cable and film marking.
