Glow in the powder, known for its ability to glow in the dark after absorbing light, is widely used in plastic coloring. These glow pigments not only enhance the value of products but also have practical uses, such as providing indicators in emergencies or at night. To understand the effects of glow powder in plastic coloring, several knowledge and technical details need to be considered.

Glow powder is increasingly used in plastic coloring. In some cases, customers may not have special requirements for the plastic’s body color and only care about its glowing color. The glowing colors of glow powder mainly include yellow-green, blue-green, and sky blue. Among these, yellow-green is the brightest and most commonly used. For plastic products with no special color requirements, simply add a suitable amount of glow powder to the plastic raw material, mix evenly, and process it to get glowing plastic products. These products will have a noticeable glowing effect in the dark, suitable for emergency exit signs, toys, decorations, and more.

In some applications, customers want plastic products to not only glow but also have a colorful appearance during the day. To achieve this, you need to use both glow powder and colored pigments in the plastic coloring process:

1. Choose Suitable Colored Pigments: First, select the right colored pigments to make the plastic products appear bright during the day.
2. Mix Glow Powder with Colored Pigments: Mix the glow powder with colored pigments in a certain ratio, ensuring an even distribution. Pay special attention to avoid uneven distribution caused by different weights of fluorescent pigments and glow powder. Adjust the ratio of fluorescent pigments to maintain both the body color and good glowing effect.
3. Conduct Small Batch Testing: To achieve the best result, it is recommended to perform small batch tests first. Adjust the ratio of colored pigments to glow powder to find the best mix. This ensures that the plastic products look good during the day and have a bright glowing effect at night or in the dark.

Sometimes, you may find that after adding the coloring powder, the body color matches your expectations, but the glowing color does not match. This happens because in the dark, the glow powder’s glowing effect and the fluorescent pigment’s coloring effect blend together. Therefore, the body color and glowing color of products with glow powder and fluorescent pigments may not be the same.

By following these methods, you can effectively combine glow powder and colored pigments to ensure that plastic products perform well both during the day and at night.
