Masterbatch pigment used, it is necessary to pay attention to the deployment of contact with the toner plastic raw materials, additives among which the selection key below.
1, pigment and resin and various additives can have repercussions, solvent resistance, migration of small, good heat resistance and the like. That is, the masterbatch can not participate in a variety of chemical reactions. Polyester plastics such as carbon black can be controlled curing reaction, it can not participate in the carbon black pigment in the polyester. Due to high temperature plastic molding process, so it should not differentiate color toner at a molding temperature heating conditions. Inorganic pigments generally good heat resistance, poor heat-resistant organic pigments and dyes, this should lead to satisfy the emphasis in the selection of the type of pigment.
2, lax sex, color toner should be in black masterbatch good. When the toner lax uneven, will affect the appearance of the article features; color toner is poor, the amount of pigment will add, material costs and progress. In the same toner resin is not the same lax and color are not the same force, so the selection of the colorant should pay attention to this point. Toner particle size is also associated with the slack, pigment particle size is smaller, the better lax, color is also strong.
3, you should know that other features of the toner, such as on the use in food, plastic toys of children on demand should be non-toxic pigment; plastic products for the electrical aspects, good electrical insulation should be selected colorant; with in terms of outdoor plastic products, should be selected for resistance to weathering and other features good pigment.
