Masterbatch

Mono masterbatches are colored pellets obtained by dispersing an unusually high amount of pigment uniformly within a resin matrix. Due to the surface characteristics of the pigments, the content of different types of pigments in masterbatches varies. Typically, the mass fraction range for organic pigments can reach 20%-40%, while for inorganic pigments, it is generally between 50%-80%.

During the masterbatch manufacturing process, the pigment particles are well dispersed uniformly within the resin, so when used for plastic coloration, it can exhibit excellent dispersibility, which is the fundamental value of masterbatch products. Additionally, the color performance of masterbatch products is customized according to the final customer's requirements, which means that coloration is one of the two primary functions of masterbatch products.

The main advantages of the masterbatch coloration process are:

 ●  Excellent dispersibility
 ●  Stable quality
 ●  Precise metering
 ●  Simple and convenient batch mixing
 ●  No bridging during feeding
 ●  Simplified production process
 ●  Easy to control, ensuring production efficiency, product quality, and performance stability
 ●  No dust, no contamination to the processing environment and equipment
 ●  Masterbatch products can be stored for an extended period.

Masterbatch products are typically used at a ratio of around 1:50 and are widely used in areas such as films, cables, sheets, pipes, synthetic fibers, and most engineering plastics. It has become the mainstream coloration technology for plastics, accounting for more than 80% of plastic coloration applications.

In addition, additive masterbatches refer to the incorporation of an unusually high amount of functional additives into the resin, resulting in a masterbatch with special functionalities. These additive masterbatches can impart properties such as aging resistance, anti-fogging, anti-static, and others to plastics, thereby expanding the new applications of plastics.
