What Are the Production Requirements and Process Flow of Masterbatch?
What Are the Production Requirements and Process Flow of Masterbatch? One of the big doubts of many friends who have just started or want to be engaged in the production of pigment masterbatches is the requirements for the production of pigment masterbatches. To explain this problem, let's start with the requirements for colorants for masterbatches. Ⅰ. Requirements for color materials for pigment masterbatches The colorant used in the color master batch must pay attention to the matching relationship between the colorant, plastic raw materials and additives. The selection points are as follows: 1. The pigment cannot react with the resin and various additives, and has strong solvent resistance, small migration, and good heat resistance. That is to say, the masterbatch cannot participate in various chemical reactions. For example, carbon black can control the curing reaction of polyester plastic, so carbon black material cannot be added to polyester. Due...
