Key Differences
Pigments are finely ground natural or synthetic particles used to impart color to other materials, such as paint, ink, plastic, and fabric. They are essentially pure colorants that need to be mixed with a binder or carrier to be applied. Pigments can be organic or inorganic, with each type offering different properties in terms of color intensity, lightfastness, and opacity. Masterbatches, on the other hand, are pre-dispersed pigments or additives encapsulated within a polymer carrier. They are used to color plastics and are produced in a granular or pellet form. Masterbatches allow for more accurate and easier handling, dosing, and mixing of the colorant with the polymer resin during the plastic manufacturing process. The polymer carrier in the masterbatch ensures better dispersion of the pigment in the final product.
While pigments are used across a broad range of industries and can color a variety of materials, masterbatches are specifically designed for the plastics industry. Pigments require careful handling and precise mixing to achieve the desired color strength and consistency. Masterbatches simplify the coloring process for plastics by providing a ready-to-use colorant solution that can be easily integrated into the plastic manufacturing process.
The choice between using pigments and masterbatches depends on the application, the specific requirements for color consistency, the type of material being colored, and the manufacturing process involved. Pigments offer versatility and are suitable for a wide range of applications but require more expertise to use effectively. Masterbatches, while specific to plastics, provide ease of use, consistency, and efficiency in the coloring process.
Both pigments and masterbatches play crucial roles in adding color to materials, but their suitability varies depending on the application. Understanding the differences between them is essential for manufacturers to make informed decisions about the most appropriate coloring method for their products.

Pigment
A pigment is a colored material that is completely or nearly insoluble in water. In contrast, dyes are typically soluble, at least at some stage in their use.
Masterbatch
Masterbatch (MB) is a solid additive for plastic used for coloring plastics (color masterbatch) or imparting other properties to plastics (additive masterbatch). A liquid dosage form is called liquid color.
Pigment
A substance used as coloring.
Masterbatch
A solid product (normally of plastic, rubber, or elastomer) in which pigments or additives are optimally dispersed at high concentration in a carrier material. The carrier material is compatible with the main plastic in which it will be blended during molding, whereby the final plastic product obtains the color or properties from the masterbatch.
