Plastic items need to be protected from sunlight during use, as do all plastic items. If plastic products are used outdoors in strong sunlight, stabilizers such as UV absorbers should be added to uncooked injection molding raw materials to prevent simple fading of plastic products when the solid is mild.
The stability of the dyes used to make plastics determines how much your product will fade. Therefore, plastic manufacturing , when determining the colorant, the high temperature resistance of the colorant should be considered. Some plastic products have poor acid and alkali resistance, such as molybdenum-chromium red, which is immune to dilute acid, but sensitive to alkali, while cadmium yellow is not acid-resistant. These two pigments and phenolic resins have a strong reducing effect on some colorants and affect the resistance of the colorants.
