Kind of difficulty with the polymer and other additives, organic pigments migration (especially plasticizers and softeners) have a great relationship. Experiments show that fertilizer anti-caking colorant products, in general, organic acid salts mobility is relatively small; the higher molecular weight less than the lower of migration. Heat resistance. Excellent heat stability as an important indicator of plastic colorants fertilizer anti-caking colorant companies, most inorganic pigments are better heat resistance, and can basically meet the requirements of plastic processing fertilizer anti-caking colorants guarantee, and organic colorants poor heat resistance. Natural colorants are driven, plants and microorganisms or processed to extract carotenoids. At present, the international market has been widely accepted and used natural pigment anthocyanin derivatives mainly marigold (lutein) and pepper dye derivative (capsanthin). In addition, the country also often use natural animals and plants as a coloring agent; such as the Ginseng powder, marigold pink, purple fertility flour, cassava leaf powder, pine needles powder, orange peel powder, Leucaena leaf meal, carrots, shrimp crab shell powder, seaweed, as livestock, poultry, aquatic products colorants.
