Color masterbatch usage

2023-09-25

Color masterbatch is a colored particle made by uniformly attaching a super constant pigment to a resin. The concentration of organic pigments in the color masterbatch is usually between 20% and 40%, while the concentration of inorganic pigments is between 50% and 80%. Because pigments are evenly dispersed in the resin during the production of color masterbatches, they have excellent dispersibility for plastic coloring.

Color masterbatch has the following advantages: dust-free particles, reduced pollution, and environmentally friendly; Convenient mixing of raw materials and accurate measurement; Improve production efficiency and product performance indicators; Reduce the amount of material used when replacing materials; Extend the shelf life of material storage; Simplify the production process and make it easy to operate.

The usage ratio of color masterbatch is generally around 1:50. Currently, it is widely used in films, cables, sheets, pipes, and synthetic fiber products, and has become the mainstream method of plastic coloring, accounting for more than 60% of plastic coloring. Color masterbatches are relatively expensive among various coloring preparations due to their complex process and high cost. Another disadvantage is that there is a certain degree of incompatibility when mixed with polymers. Therefore, when selecting the carrier for coloring agents, it should be of the same type as the polymer to be colored.

The color masterbatch has a high pigment content, bright colors, and good brightness. When used, the melt mixing has dispersibility and thermal stability, and the product has a high mechanical strength retention rate. This product has a wide range of colors and can be customized according to customers' color needs.

Application fields: chemical fibers (carpets, polyester, polypropylene, non-woven fabrics, etc.), blown film products (packaging bags, casting films, multi-layer composite films, etc.), blown molded products (pharmaceutical and cosmetic containers, lubricants and paint containers, etc.), extruded products (sheets, pipes, cables and wires, etc.), injection molded products (automotive accessories, electrical appliances, building materials, daily necessities, toys, sports goods, furniture, etc.).
