Pritty pearlescent pigments are compatible with transparent and semi-transparent plastic resin, and bring a special chroma and fancy visual effect to the final application. Pritty pearlescent pigments are widely applied in packages of cosmetic products, toys, decorative materials, and various thin film plastic products.
Tips to achieve the optimal pearl effect:
Plastic resin must be transparent or semi-transparent. High gloss plastic resin shows pearlescent effect the best.
Use pigments with good transparency to mix with pearl pigments
Try not or reduce damage to pearlescent pigments during processing
Pearlescent pigments need to be fully dispersed and pearlescent pigment flakes need to be parallel to the plastic surface to obtain the optimal pearl effect
The plastic characteristics and manufacturing process will affect the final products chroma/luster. The normal pearlescent pigments dosage in plastic is 0.5-2%. For thin film or thin plastic products, the dosage should increases to 4-5%.
The best way to colour plastic resin is using master batch. Master batch can be made either from coarse or fine resin powder. Polymers with high melt flow index, strong fluidity and molecular weight lower than the resin are recommended, as the addition of pearl pigments will decrease its melt flow index.
Tips to use Special effect mater batch:
Avoid long time and sharp stirring to protect pearl platelets crystal structure and ensure the final pearl effect.
Increase the pressure to improve mixing efficiency and ensure pearl pigments are fully dispersed.
Increase the temperature in the allowable range and reduce the melt viscosity to minimize the damage to pearl pigments.
The Mould finish gloss, mould design and manufacturing process could affect the pearlescent pigment flake distribution which will affect the final pearl effect.
