Laser Foaming White Marking Masterbatch: Achieving Permanent High-Contrast Marking on Dark Plastics
Runpacet White Marking Masterbatch utilizes laser energy to instantaneously melt the plastic surface while activating specialized foaming additives within the material. These additives rapidly decompose, releasing micro-gases that form a uniform, dense matrix of micro-bubbles in the molten polymer. The bubbles effectively scatter incident light, causing the marked area to appear as a vivid, stable white – similar to the microstructure of snow or foam. This technology is specifically engineered to create high-contrast, permanent markings on dark substrates.
Marking Effects and Characteristics
White Marking Masterbatch enables clear, precise white text and patterns on black or dark-colored plastic surfaces after fiber laser marking. The marked area exhibits a delicate, matte-white texture that creates strong visual contrast against both glossy and matte dark backgrounds. The markings demonstrate excellent adhesion and wear resistance, becoming an integral part of the product that meets long-term industrial identification requirements.
Core Technical Advantages
- Excellent visual contrast: Produces prominent, easily legible white markings on dark backgrounds
- Permanent durability: Markings bond firmly with the substrate, resistant to abrasion and chemical wiping.
- Fine pattern reproduction: Supports complex graphics, miniature text, and high-resolution QR codes.
- Broad material compatibility: Suitable for most dark-colored engineering plastics and general-purpose plastics.
- Green production process: Requires no inks or consumables – a non-contact, clean processing technology.
APPLICATIONS
This technology is particularly suitable for:
Industrial components (indicator icons on appliance buttons).
Electronic products (markings on router and remote control housings).
Automotive interior components (part numbers and safety identification).
Product traceability (barcodes, QR codes, and other identification needs).
The technology delivers excellent visual contrast and permanence while supporting detailed pattern reproduction across various materials. As a non-contact, consumable-free process, it also complies with green production requirements.
