LaserMark-SF is a laser-responsive functional additive that enables light, foamed contrast marking on dark or high-absorption engineering plastics. It generates clear, durable markings through controlled surface foaming rather than pigment burning, ensuring high readability without compromising polymer performance.
LaserMark-SF is a laser-responsive functional additive designed to generate light or foamed contrast markings on dark or high-absorption engineering plastics.
2. How does LaserMark-SF create contrast?LaserMark-SF works through controlled surface foaming under laser irradiation, producing light-colored marks without relying on pigment burning or carbonization.
3. What types of plastics are suitable for LaserMark-SF?LaserMark-SF is suitable for dark-colored or carbon-filled engineering plastics such as PP, ABS, PC, PA and related compounds.
4. Which laser systems are compatible?LaserMark-SF performs effectively under common fiber (1064 nm) and green (532 nm) laser systems used in industrial marking.
5. Is LaserMark-SF a pigment or colorant?No. LaserMark-SF is a functional laser-activation additive and does not act as a color pigment or filler.
6. Will LaserMark-SF affect mechanical or surface properties?At optimized addition levels, LaserMark-SF maintains the mechanical integrity and surface quality of the base polymer.
7. How does LaserMark-SF differ from LaserMark-W?LaserMark-SF is optimized for light or foamed markings on dark substrates, while LaserMark-W is designed for dark, high-contrast markings on light or low-absorption plastics.
8. Can LaserMark-SF be used together with other functional additives?Yes. LaserMark-SF can be formulated alongside conductive additives, fillers or stabilizers when proper formulation balance is maintained.
