Safety first: High-performance plastics from Evonik are used in steering gears as well as in brake lines for trucks, while our oil additives for shock absorbers take care of ensuring a comfortable ride. Various solutions from Evonik enable the efficient production of more environmentally friendly ‘green tires’ using recycled plastics which offer low rolling resistance and abrasion but  maintains wet grip performance. 

Shock Absorbers & Air Suspension

The superior wax crystallization control of VISCOPLEX® pour point depressants (PPDs) guarantees optimized oil flow behavior in cold climates, so vehicles and equipment can operate smoothly in adverse weather.

VISCOPLEX® viscosity index improvers (VIIs) feature polymers that contribute to higher viscosity at high temperatures and offer minimal viscosity contribution at lower temperatures. They are used to formulate multigrade engine oils, transmission fluids, hydraulic fluids, gear oils and other industrial lubricants.

Tires & Rubbers


1,3 butadiene is used as a monomer for synthetic rubber like tires

In COUPSIL® products the silica is already pre-reacted with the silane. This makes the application of the Silica/Silane-system much simpler, because the complex silanization reaction in the mixer is obsolete.

POLYVEST® ST enables to improve the overall performance of silica-reinforced tire tread compounds in combination with sulfur silanes like Si 69® or Si 266®. Its application allows to significantly reducing the rolling resistance, which has been indicated by reduced PAYNE effect and tan delta at 60 °C in GREEN Tire and truck tire treads compounds.

Si 69® is a bifunctional, sulfur-containing organosilane for rubber applications like low rolling resitance Green Tires 

The highly dispersible silica (HDS) ULTRASIL® enable the  production of rubber compounds with low dust and easy mixing. It provide solutions for the compounder to improve the performance like e.g. wet traction and braking, wear and rolling resistance properties and in that way higher fuel efficiency and CO2 emission reductionof so called Green Tires.

VESTENAMER® improves compatibility, mixing, shaping, and product performance of rubber compounds. The world’s most versatile rubber additive can be used for manufacturing of tires, technical rubber goods or for efficient rubber recycling.

Other Specialities

Adhesion of rubber to fabric or steel cord for tires can be significantly improved with the so called RFS-system (Resorcinol Formaldehyde Silica). COFILL® 11 combines the resorcinol with the silica, so the handling  is much safer but  the excellent adhesion is the same.

TAC and TAICROS® are mainly used as crosslinking additives in peroxide or electron beam induced crosslinking to increase chemical resistance of rubber or thermal and chemical resistance in plastic materials

The 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.
