1. To improve the dispersibility of pigments in products, it is necessary to refine the pigments during the production process of color masterbatch to improve their dispersibility and coloring power. The carrier of the color masterbatch is the same as the plastic variety of the product, and has good compatibility. After heating and melting, the pigment particles can be well dispersed in the plastic of the product. 2. It is beneficial to maintain the chemical stability of pigments. If pigments are used directly, due to the direct contact with air during storage and use, the pigments will experience water absorption, oxidation, and other phenomena. After becoming the color masterbatch, the resin carrier will isolate the pigments from air and water, which can maintain the quality of the pigments for a long time. 3. Ensure the stability of the product color. The color masterbatch particles are similar to the resin particles, making measurement more convenient and accurate. When mixed, they will not adhere to the container, and the mixing with the resin is also more uniform. Therefore, it can ensure the stability of the addition amount, thereby ensuring the stability of the product color. 4. Protective pigments for the health of operators are generally in powder form, which can easily fly when added and mixed. Inhalation by the human body can affect the health of operators. 5. Keep the environment clean. 6. Easy to use.
