Plastic Additives

Improving the functionality of pigments, fillers and flame retardants without increasing the cost? Evonik TEGOPREN® surface treatment portfolio is here for you.

Evonik TEGOPREN® organic modified siloxanes are widely used by the manufacturers of pigments, fillers, and flame retardants to improve the products hydrophobicity and allow for an optimum dispersion in the polymer matrix. 

In a typical thermal conductive polymer compound application, functional fillers such as Al2O3, give a higher thermal conductivity efficiency, after surface treatment with either TEGOPREN® 6875 or TEGOPREN® 6879.

Besides 100% active products, Evonik also offers emulsions that can be applied in a aqueous step to the slurry or filter cake.

High-performance plastics contribute to the efficient use of resources as they help to reduce weight without affecting mechanical, optical or haptic characteristics. However, not all questions on the sustainable use and the recycling of such plastics have been fully answered yet. This is where Evonik comes in; we work intensively to develop strategies and solutions on the key topics of the plastics industry.
