Fillers, Pigments & Colorants
Evonik's dispersing additives are unrivalled in achieving high-quality masterbatches and liquid colorants by providing an optimum dispersion of pigments or fillers.
Pigments, fillers, and colorants are all important components for many plastics formulations, giving the final product the desired appearance or the desired technical features. The problem: The particles are usually too hydrophilic, making it difficult to mix them with the polymer matrix.
Many manufacturers of these raw materials rely on our additives, which make targeted changes to the surface properties of the particles so that they are much easier to process. Organically modified siloxanes such as TEGOPREN® 6875 or TEGOPREN® 6879 are used by the manufacturers of pigments, fillers, and flame retardants to make the surface of their particles more hydrophobic.
A further advantage: In contrast to others, the special additives we provide also improve the dispersion properties of the products. This means that compounders can work the particles into the polymer matrix more easily. Our special additives perform their positive effect via two mechanisms: Firstly, the plastics formulations can be manufactured especially efficiently – because the same effect can be achieved with a lower volume of surface-treated particles – or secondly, the products with superior material properties can be manufactured because the same volume of particles has a more powerful effect.
For liquid colorants production, our dispersing aids TEGO® STO V, TEGO® STO 85 V and TEGOMER® DA 800 can be used as a carrier system at the same time.
