Achieve stable dimensions in any color
Pigments nucleate polypropylene to different degrees, which makes it difficult to mold parts with identical dimensions. Some pigments also have anisotropic shrinkage properties that can cause part warpage.
Milliken solutions allow converters to override the nucleation effect of pigments so that they can produce a variety of colored parts with identical dimensions using the same mold and production conditions. This reduces design complexity and increases the quality and consistency of the final product offer.
