This pigment is treated with special surface modification, which improves the dispersibility in plastic substrates and avoids color spots on plastic products caused by pigment agglomeration. It can withstand high temperature up to 280℃, adapting to common plastic injection molding and extrusion processing temperatures. The migration fastness reaches level 5, meeting food contact safety requirements, and has no peculiar smell, which will not pollute plastic products. The hue is stable and consistent, with small batch color difference, solving the pain point of large batch color difference of traditional pigments, and improving the appearance quality of plastic products.
The appearance is bright lemon yellow powder, with CIE color values a*:12.5±1.0, b*:32.0±1.5, L*:82.0±0.8. The heat resistance is 280℃ without discoloration, the migration fastness conforms to GB 9685-2016 standards, the lead content is less than 10ppm and cadmium content is less than 5ppm. The average particle size is 0.5-1.0μm, the oil absorption is 28-35g/100g, and it is packed in 10kg double corrugated boxes with PE moisture-proof bags. It should be stored in a cool and dry place at 5-35℃, with a shelf life of 2 years.
This pigment is mainly applicable to food contact plastic packaging, children's toy plastics, household daily plastic products and automotive interior plastic particle coloring. The target industries include plastic manufacturing, toy manufacturing and food packaging industry. Typical application scenarios include coloring of disposable lunch box plastics, color matching of children's building block plastic raw materials, and coloring of automotive dashboard plastic modifiers. It can endow products with uniform and stable warm yellow hue while meeting compliance and safety requirements.
