Masterbatch is a new type of special colorant for polymer materials, also known as pigment preparation. It is composed of three basic elements: pigments or dyes, carriers and additives. It is an aggregate obtained by uniformly loading super-constant pigments or dyes in the resin. It can be called pigment concentrate, so its tinting strength is high. on the pigment itself. How do we do masterbatch mixing?
The method of mixing masterbatch
1. Replace the color masterbatch. The effect of color masterbatch on injection molded plastic parts is complex. While it's rarely something to consider when planning a project, it should be addressed during the material selection phase. This process requires several important steps. The choice of colored resin will depend on factors including the actual resin involved and the end application, which may determine durability needs, environmental factors and the cost of colored plastic production.
2. Pigments. Colorants/masterbatches can be dyes or pigments, or primary colors. Pigments are not soluble in resin, whereas dyes go into resin solution and mix easily. They are used for coloring clear plastics and where intense coloring is required. Dyes provide vibrant color without blurring surface imperfections like pigments. Dyes also tend to perform poorly in outdoor applications.
Colorants may be partially soluble or insoluble. Organic pigments are more efficient than inorganic pigments in tinting power and color fastness, producing brighter and glossier colors at lower percentages. They can also be used to color clear plastics. Inorganic pigments are less fluid than organic dyes and pigments and are therefore used to color plastics that require high transparency. Compared with dyes and organic pigments, inorganic pigments also have excellent heat resistance and weather resistance.
3. Effects of colorants/masterbatches. The addition of masterbatch colorants to resins can affect the properties of the resinous part, so it is important to consider the compatibility between the chemical composition of the polymer and the chemical composition of the colorant. The effect of colorant on polymer properties also depends on the amount of primary colorant. Certain compounds in colorants destroy the chemical properties of the polymer and impair its original properties, such as impact resistance. The high temperatures used in the injection molding process also affect the degree to which the colorant affects the polymer.
4. There are also many different plastic coloring methods including mastering, blending, surface coating and dry blending. The method used affects the mechanical properties of the plastic. For example, in a synthetic method, particles of natural color are mixed with a mixture of particles having a high pigment content. Since most polymers do not mix with other polymers, care must be taken to ensure material compatibility.
