Plastic Additives

Automotive & Transportation

Evonik’s performance additives for engineering resins and silicone rubber compounds offer the essential properties the automotive industry requires, including the new E-mobility market.

TEGOMER® - Evonik’s organic modified siloxane portfolio - helps to improve the flowability and wetting of highly filled compounds, such as Polyamide compounds in under the hood applications, as well as the glossiness and scratch resistance of compounds, such as high gloss PMMA or PC/ABS compounds used for auto interiors.

Our TEGOSIL® Thermal management portfolio improves the heat resistance and heat transfer performance of silicone rubber formulations, helping the automotive and transportation industries to meet new industry standards such as the latest EN 45545 standard.


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.

This overview includes our product portfolio of additives for masterbatchers, compounders and converters. We offer a broad range of products such as colorants, adjuvants for surface treatment as well as specialty additives for miscellaneous applications.
