Masterbatch is the most common plastic coloring method and is widely used in the plastic processing industry. Dispersion is one of the most important performance indicators of masterbatch. Obviously, dispersion has a vital impact on the quality of plastic products.

The amount of color masterbatch added to the final resin is generally 2%-5%. If the color masterbatch is mixed and added correctly, the content of the carrier resin in the final mixture will account for 1%-3% or more. This makes it the most abundant additive in the additive family, so some details should be paid attention to when selecting the carrier resin. For example, users' requirements for color, color stability, environmental requirements, and the role of masterbatch in the final product, etc., make the formulation of masterbatch increasingly complex.

Factors affecting plastic shrinkage include plastic species, molding conditions, mold structure, etc. Different plastics have different shrinkage rates. In addition, the shrinkage rate of plastics has a lot to do with the shape of the plastic part, the complexity of the internal structure, and whether there are inserts.
