Color masterbatch, full name color concentrate, is a polymer composite material made by mixing and processing high-concentration pigments or dyes, carrier resins, dispersants and other additives. Widely used in the plastic processing industry, it serves as the core material for coloring plastic products. Compared with directly adding pigments, color masterbatch boasts advantages such as uniform coloring, convenient use and strong environmental friendliness, and has become an indispensable key raw material in plastic processing technologies like injection molding, film blowing and pipe extrusion.

Core Function of Color Masterbatch: Precisely “Coloring” Plastic Products

In plastic production, pure resin substrates are mostly transparent or white. To obtain plastic products with rich colors, a coloring process is required, and color masterbatch is developed exactly to meet this demand.

Its core function is to endow plastic products with stable and bright colors, while solving a series of problems caused by direct pigment addition. When pigments are added directly, the pigment particles are difficult to disperse uniformly, which is likely to cause color spots and streaks on the finished products; moreover, the dust pollution is severe, endangering the health of operators. In contrast, after special processing, the pigments in color masterbatch are fully wrapped by carrier resins, featuring excellent dispersibility that ensures consistent color of plastic products and greatly reduces the color difference rate. In addition, high-quality color masterbatch can also improve the weather resistance and light fastness of plastic products, delay the fading and aging of finished products, and extend their service life.

Extended Functions of Color Masterbatch: Optimizing Processing Efficiency and Product Performance

Beyond the basic coloring function, color masterbatch can also play multiple extended roles in plastic processing, helping enterprises improve production efficiency and product quality.

First of all, it improves processing fluidity. The dispersants and carrier resins added in color masterbatch have good compatibility with plastic substrates, which can reduce melt viscosity, make the raw materials flow more smoothly in injection molding and extrusion equipment, reduce problems such as mold blocking and material sticking, and improve production continuity. Secondly, it reduces production costs. Color masterbatch has a high concentration, with an addition ratio usually only 2%-5%, which is easy to measure and can reduce raw material waste. Meanwhile, the use of color masterbatch does not require additional coloring equipment, saving equipment investment and labor costs. In addition, some functional color masterbatch can also endow plastic products with special properties. For example, antistatic color masterbatch can reduce static electricity on the surface of plastic products, and antibacterial color masterbatch can inhibit bacterial growth, meeting the needs of special fields such as medical treatment and food packaging.

Main Application Fields of Color Masterbatch

The application of color masterbatch covers the entire industrial chain of plastic processing, and almost the production of all colored plastic products is inseparable from it.

In the pipe and profile field, color masterbatch is often used for coloring pipes such as PVC and PE. For instance, the blue of water supply pipes and the black of drainage pipes not only meet the requirements of appearance identification, but also enhance the UV resistance of the pipes. In the packaging field, food packaging films, shopping bags, plastic bottles and other products achieve diverse colors through color masterbatch, which also complies with the safety standards for food contact materials. In the automotive and home appliance field, automotive interior parts and home appliance shells have extremely high requirements for color consistency; color masterbatch can accurately match the designed colors and ensure the temperature resistance and scratch resistance of the products. In addition, color masterbatch is also widely used in industries such as toys, wires and cables, and non-woven fabrics, endowing various plastic products with rich colors and stable performance.

In conclusion, color masterbatch is not only a “colorant” for plastic products, but also an important additive for improving production efficiency and ensuring product quality. With the development of the plastic processing industry, color masterbatch is also upgrading towards high concentration, high performance and environmental protection, providing strong support for the innovative development of plastic products in various fields.
