Masterbatch

Overview

Masterbatch refers to a concentrated substance made by resins with excessive additives. In plastic manufacturing, the initial attaching process is replaced by adding proportional masterbatches, making it efficient and more environmental friendly.

Main applications:

Color masterbatch: The pigment is dispersed and uniformly attached to the resin to obtain color masterbatch. Due to the surface characteristics of pigments, the content of different pigments in the masterbatch varies. The mass fraction of organic pigments ranges from 20% to 40%, while inorganic pigments generally range from 50% to 80%. Color masterbatch products can be applied in film, cables, sheets, pipes, synthetic fibers, and the vast majority of engineering plastic applications.

Functional masterbatch: Refers to the concentrate of various plastic additives. For example: pearl masterbatch, metal pigment masterbatch (for automobiles and household appliances), double anti masterbatch (for agricultural films), anti-static masterbatch (for packaging films), anti-fog masterbatch (for agricultural films), antibacterial masterbatch (for medical and daily life products, and etc.).

Flame retardant masterbatch: Masterbatch produced by mixing flame retardants and resins. Some plastics are flammable, especially those with high carbon content. This material is properly processed so it can be used in fire hazard environments. It is applied in electronics,construction, automotive,and aviation industries.

Filling masterbatch:

The polyolefin filling masterbatch consists of three parts: carrier resin, fillers, and various additives. Its performance and cost mainly depend on the carrier resin’s content, which generally contains 10% to 25%. The carrier resin should have good compatibility with the filler. Filling masterbatch can be used for processing plastic films, hollow products, pipes, sheets, injection molded products, and plastic fast food boxes. It can improve the strength, anti-aging and other properties of products and reduce costs.
