What are the color requirements for PP masterbatch?
(1) The coloring material cannot react with the resin and various auxiliary agents, and has strong solvent resistance, small mobility, and good heat resistance. That is to say, PP masterbatch cannot participate in various chemical reactions. If carbon black can control the curing reaction of polyester plastic, carbon black can not be added to the polyester.
Since the molding temperature of the plastic product is high, the coloring material used for the PP masterbatch should not decompose and discolor under the molding heating temperature condition. Generally, inorganic pigments have good heat resistance, and organic pigments and dyes have poor heat resistance, which should be paid enough attention when selecting colorant varieties.
(2) The dispersibility and coloring power of the colorant should be good. When the color material is unevenly dispersed, it will affect the appearance performance of the product; when the coloring power of the color material is poor, the amount of color material will increase and the material cost will increase. The dispersibility and tinting strength of the same colorant in different resins are not the same, so you should pay attention to this when selecting the colorant.
The particle size of the colorant used in the PP masterbatch is also related to the dispersibility. The smaller the particle size, the better the dispersibility and the strong coloring power.
(3) It should be understood that other properties of colorants, such as plastic products used in food and children's toys, should be non-toxic; for plastic products used in electrical appliances, colorants with good electrical insulation should be selected; For outdoor plastic products, colorants with good weathering resistance should be selected.
