Pearlescent pigments are used in clear and translucent plastic resins, and the use of pearlescent pigments provides a fascinating color vision. Generally, the better the transparency, the more the resin can fully exhibit the unique gloss and color effects of pearlescent pigments. For less transparent resins (PC/PVC, etc.), the pearlescent luster and hue can be fully exhibited due to the processing characteristics of these resins.

Therefore, it is widely used in the plastics industry, including injection molding, blow molding, plastic molding, casting, masterbatch and other plastic processing processes, such as manufacturing cosmetic containers, shampoo containers, food and pharmaceutical containers, tubes, household plastic products , toys, buttons, sandals, construction plastic products, home plastic decorations, and so on.

Pearlescent pigments are translucent. In the course of application, it is necessary to pay attention to its optical function and use it to achieve outstanding pearlescent effect, because pearlescent pigments have different characteristics from ordinary pigment processing.

Generally, to get better pearlescence, you should pay attention to the following conditions:

1. The transparency of the colored plastic resin is better.

2. Mix as much as possible with a good transparency pigment and pearlescent pigment.

3. Reduce the damage to pearlescent pigment tablets as much as possible during processing.

4. Fully disperse the pearlescent pigment, and the pigment flakes are oriented parallel to the plastic surface.

In addition to the above conditions, the characteristics and processing methods of plastic resins will also affect the gloss function of the final product.
