The role of masterbatch
12/26/2018


          Masterbatch is mainly used to color plastics and is an essential element in colored plastics. The coloring material is made by mixing the resin and the coloring agent and is granulated into a colored plastic, and then used in a molding process.
         The masterbatch makes the pigment have better dispersibility in the product, and the pigment must be refined in the production process of the masterbatch to improve the dispersibility and tinting strength of the pigment. The carrier of the special color masterbatch is the same as the plastic of the product, and has good matching property, and the pigment particles can be well dispersed in the plastic of the product after heating and melting. Masterbatch helps maintain the chemical stability of the pigment
         When the pigment is used directly, the pigment will absorb water and oxidize due to the direct contact of the pigment during storage and use. After the masterbatch is formed, the pigment can be separated from the air and moisture by the resin carrier. The quality can be kept for a long-term. At the same time, the masterbatch can guarantee the stability of the color of the product.
