Why Can Fluorescent Pigment Build Up on the Screw During Injection Molding?

Screw build-up during fluorescent plastic coloring is mainly related to the resin-based pigment structure, relatively high dosage and differences in melting behavior.

Many daylight fluorescent pigments contain colorants incorporated into a polymeric resin matrix. During injection molding, this resin phase softens and can contact steel surfaces inside the screw and barrel. Polymer-processing studies confirm that deposits can form at polymer-melt/steel interfaces and may later detach as localized spots in molded parts.[1]

Fluorescent pigments are also commonly used at higher levels than many conventional pigments. Based on long-term production experience, typical dosage is around 1–2%, compared with approximately 0.02–0.1% for some conventional pigments. This increases the amount of resin-based colorant passing through the screw and the possibility of local accumulation.

In practical processing, resin-based fluorescent pigments generally enter a molten or strongly softened state at approximately 140–170°C. If this occurs before the surrounding plastic is fully molten, the softened pigment resin may contact and adhere to the screw surface before a homogeneous melt is formed.

Color streaks are not always caused by deposits alone. Masterbatch formulation, screw geometry and processing conditions can also affect pigment dispersion and color homogeneity.[2]

For yellow green fluorescent pigment used in fluorescent masterbatch and injection-molded plastics, controlling dosage, resin compatibility and processing conditions helps reduce screw build-up, spots and uneven coloration.
