LaserMark-W™ Laser Marking Additive for Engineering Plastics
LaserMark-W is a laser-responsive functional additive that enables high-contrast, permanent laser marking on engineering plastics without acting as a color pigment or filler.

Introduction
LaserMark-W is a laser-responsive functional additive designed to enable high-contrast, permanent laser marking on engineering plastics. It is optimized for applications where background brightness or low laser absorption limits contrast formation. LaserMark-W functions as a laser-activation agent rather than a color pigment or filler, ensuring marking performance without compromising base polymer properties.

Processing & Integration Notes

Compatibility with Conductive Additives such as SWCNT Slurry

LaserMark-W™ is a laser-responsive functional additive for engineering plastics. It is designed for permanent laser marking under fiber and green laser systems, and is not a color pigment or filler. • Enables high-contrast laser marking at low additive loading • Converts laser energy into localized optical contrast • Compatible with fiber (1064 nm) and green (532 nm) laser systems • Does not migrate, bleed, or affect surface finish • Maintains mechanical and electrical properties of base polymers • Suitable for standard compounding and injection molding processes
Application area

Application Areas

  • Light-colored or natural engineering plastics requiring dark, high-contrast laser identification
  • Injection-molded PP, ABS, and PC components where ink or label-based marking is not acceptable
  • Electronic housings and connectors requiring permanent traceability on bright substrates
  • Automotive and industrial plastic parts exposed to wear, heat, or chemicals
  • Precision plastic components where post-labeling or printing is not feasible
