1、 Definition and purpose

　　Color masterbatch, as the name suggests, is a special particle specifically used to color plastics. It is usually made by mixing pigments, carrier resins, and other additives, and through accurate proportioning and processing techniques, the color masterbatch can be uniformly dispersed when the plastic melts, thereby achieving the effect of coloring the plastic. Color masterbatch is widely used in the production of various plastic products, such as packaging materials, pipelines, wires and cables. It not only adds rich colors to the products, but also increases the added value of the products.

　　Plastic pellets are a basic plastic raw material, usually composed mainly of resin. It is made into granules through processes such as melting, plasticizing, and extrusion, making it convenient for storage and transportation. Plastic pellets are the basic raw materials for manufacturing various plastic products, such as plastic bags, plastic containers, plastic pipes, etc. It has a wide range of applications, covering almost every aspect of people's lives.

　　2、 Nature and Characteristics

　　A significant characteristic of color masterbatch is its coloring performance. It can maintain color uniformity and stability during the plastic melting process, and is not easily faded or discolored. In addition, color masterbatch also has excellent dispersibility, which can be uniformly dispersed in plastics, avoiding phenomena such as color spots or stripes. At the same time, the weather resistance and migration resistance of color masterbatch are also excellent, which can meet the needs of different plastic products.

　　The main characteristics of plastic pellets are their plasticity and processability. It has good melt flowability and formability, and can be plasticized into various shapes after heating. In addition, plastic particles also have excellent mechanical properties and chemical stability, which can meet the performance requirements of different plastic products.

　　3、 Selection and Application

　　When selecting color masterbatch and plastic pellets, it is necessary to consider the specific plastic products and applications. For plastic products that require coloring, appropriate color masterbatch should be selected to ensure uniform and bright colors of the product. At the same time, it is necessary to consider the weather resistance, migration resistance, and other properties of the color masterbatch to ensure that the product can maintain a good appearance in different environments.

　　For plastic products that do not require coloring, it is important to choose appropriate plastic particles. When selecting plastic pellets, factors such as melt flowability, formability, and mechanical properties need to be considered to ensure the quality and performance of the product.
