Industry Teams

Products & Solutions

With its wide product portfolio, local service, and application technology expertise accumulated over decades, Evonik is a strong partner to the tire and rubber industries with production sites worldwide.


ULTRASIL® is indispensable in tire manufacture and the production of industrial rubber goods. It is an essential component in the treads of what is known as Green Tires, which are distinguished from conventional tires particularly by low rolling resistance and significantly improved grip (road holding). In industrial rubber goods silica is used, for example, to reduce hysteresis loss in conveyor belts or as an active filler in colored rubber articles or in products with food contact.
The spectacular success of precipitated silica in tire applications would not have been possible without sulfur silanes. Hydrophilic silica does not easily mix with hydrophobic rubber; a sulfur silane must therefore be added to bind them chemically. This was achieved for the first time by means of Evonik’s Silica / Silane technology – and ULTRASIL® VN 3 and Si 69® are the result of this development.

The desire of tire and MRG manufacturers for improved processability of rubber compounds has resulted in a continuous expansion of Evonik’s product range. For example, elastomers and additives can be more easily, and above all more efficiently, mixed through the addition of the special process additive VESTENAMER®. POLYVEST® liquid polybutadienes reduce rolling resistance further; in this case it is even possible to dispense with mineral oil as a plasticizer.
