Color Masterbatch Compound

A color masterbatch, or color concentrate, is a granule used for coloring thermoplastics. It consists of one or more colorants and a polymer-specific carrier resin. The composition of a color masterbatch is called its recipe.

Colorants are classified into several categories: organic dyes, organic pigments, and inorganic pigments.

Dyes are soluble in plastics and can therefore be used for transparent coloration. Pigments remain in their original particle form inside the plastic and need to be dispersed within the plastic.

The recipe for a specific color masterbatch is developed in our laboratory based on a customer’s requirements.

A color masterbatch may contain up to 60% colorant. In the subsequent production process, the colorant is introduced into the melted plastic.

Color masterbatch is applied in many fields of the plastic industry that create convenience and effectiveness for the production: 

+ Film blowing, film extrusion (packaging film, elastic film, agricultural and construction film, diaphragm, garbage bag, multi-layer bag)

+ Blowing Film

+ Injection molding: home appliances, toys, garden furniture, potted plants, buckets, boxes, electronics, barrels, boxes ...)

+ Blow molding of bottles

+ Extrusion of sheets, fibers, and cables

In the variety of applications and wide range of plastic products, the color chart is also very wide, each color has many shades. To get the exact color for your product, the best solution is to analyze the color from the sample plastic product.
