Color is one of the most expressive elements in design and is crucial for aesthetic enjoyment. Masterbatches, which carry colorants for plastics, play a key role in adding vibrancy to products in our daily lives. In addition to coloring, filler masterbatches are essential in plastic production to reduce costs, improve production efficiency, and enhance the rigidity of the final product. However, both color masterbatches and filler masterbatches often face significant processing challenges that can affect product quality and increase production costs.

Common Processing Issues in Color and Filler Masterbatches

Color masterbatches, also known as color concentrates, are used to color plastics by evenly dispersing pigments within the polymer matrix. To achieve uniform pigment dispersion and prevent clumping, dispersants are often required. Similarly, filler masterbatches, which consist mainly of fillers, rely on dispersants to improve processing flowability and ensure even distribution of fillers within the polymer. However, many dispersants fail to effectively address key issues during production, leading to increased costs and production challenges:

 1. Pigment and Filler Aggregation: This results in uneven color in the final product and the formation of visible hard particles or “clouding.”

 2.Poor Dispersion and Material Blockage: Insufficient dispersion can lead to material accumulation in the injection mold, causing flow issues.

 3. Inadequate Color Intensity and Colorfastness: Some masterbatches do not provide the desired color strength or durability.

 What’s Really Going Wrong?

Most traditional dispersants, such as PE wax, are not effective at higher processing temperatures, leading to poor pigment and filler dispersion. This directly impacts color quality, processing efficiency, and overall product durability. You need a solution that can handle the high processing demands of today’s color and filler masterbatches while ensuring a flawless finish.
