1、 Function and purpose

　　Color masterbatch is a special plastic particle containing pigments or dyes, mainly used to color plastic products. By adding color masterbatch, plastic products can present a rich and colorful color, meeting the aesthetic needs of different consumers. The pigment or dye of color masterbatch is evenly dispersed and not easily faded, thus ensuring the long-term stability of plastic products.

　　The filling master batch is a special plastic particle containing inorganic or you machine filler, which is mainly used to improve some physical properties of plastics, such as hardness, strength, wear resistance, aging resistance, etc. Filling the filler in the masterbatch can increase the volume of plastic, reduce production costs, and also improve the thermal conductivity and insulation properties of plastic.

　　2、 Preparation process

　　The preparation process of color masterbatch mainly includes the selection and dispersion of pigments or dyes, the selection and melting of carrier resins, melt blending, cooling and crushing, and other steps. During the preparation process, it is necessary to ensure the uniform dispersion of pigments or dyes in order to achieve good coloring effects.

　　The preparation process of filling masterbatch mainly includes the selection and treatment of fillers, the selection and melting of carrier resins, melt blending, cooling and crushing, and other steps. During the preparation process, it is necessary to control the particle size and distribution of the filler to ensure stable performance of the filling masterbatch.

　　3、 Application Fields

　　Color masterbatch is widely used for coloring various plastic products, such as household appliance casings, automotive parts, packaging materials, building materials, etc. The use of color masterbatch not only beautifies the appearance of plastic products, but also enhances the added value and market competitiveness of the products.

　　Filling masterbatch is mainly used to improve the physical properties of plastics and is widely used in fields such as plastic pipes, plastic sheets, and plastic packaging materials. The addition of filling masterbatch can improve the durability and service life of plastic products, reduce production costs, and meet the needs of different fields.

　　Color masterbatch and filler masterbatch both play important roles in the plastic processing industry, but they have significant differences in terms of function, application, and preparation process. Masterbatches are mainly used to color plastic products, and the preparation process requires ensuring the uniform dispersion of pigments or dyes; Filling masterbatch is mainly used to improve the physical properties of plastics, and the particle size and distribution of fillers need to be controlled in the preparation process. In practical applications, appropriate additives should be selected according to different needs and purposes to achieve the desired performance of plastic products.
