1. To make pigments have better dispersion in the products: In the production process of masterbatch, the pigment must be refined to improve the dispersibility and coloring power of the pigments. The carrier of the special masterbatch is the same as the plastic of the products. Good compatibility, pigment particles can be well dispersed in the plastic of the product after heating and melting.
2. It helps to maintain the chemical stability of the pigment: When the pigment is used directly, the pigment will absorb water, oxidize, etc. due to the direct contact of the pigment with air during storage and use. , moisture isolation, can make the quality of pigments long-term unchanged.
3. To ensure the stability of the color of the product: The masterbatch particles are similar to the resin particles, which is more convenient and accurate in metering. When the mixture is mixed, it will not adhere to the container, and the mixture with the resin is also more uniform, so the stability of the addition amount can be ensured. Ensure product color stability.
4. To protect the health of operators: Pigments are generally powdery, easy to fly when added and mixed, and will affect the health of operators when inhaled.
