Evonik for Automotive Industry
As the wheels of progress propel us towards a brighter future, it is crucial to prioritize environmental impact. Evonik offers sustainable solutions for the automotive industry that will drive us towards a greener tomorrow.
Electric vehicles
AEROXIDE® metal oxides are used as additives in Li-ion batteries to increase the performance, lifetime, and safety of the battery.
The carbon-covered silicon Siridion® Black is used as additive for anodes in lithium-ion batteries to increase the LIB capacity by high stability and oxidation protection of the anode itself.
TEGO® Surten E series are the process enablers which help contribute to further improvements in the production of lithium-ion batteries which yield better electrical performance and lower overall costs.
VESTAMID® polyamide 12 (PA12) is a UL94 flame retardant polymer that provides excellent high-voltage insulation properties for power busbar applications according to future safety requirements in EV.
VISCOBASE® dielectric thermal management fluids for longer battery life, thermal efficiency, and safe operation.
Tires
POLYVEST® ST significantly reduces the rolling resistance of the optimized green tire by 15% without affecting wet grip and abrasion resistance, thereby improving driving safety and fuel efficiency.
Si 69® is a bifunctional, sulfur-containing organosilane for rubber applications like lowering rolling resistance, improving wet grip, and reducing fuel consumption in Green Tires.
ULTRASIL® grades in tire tread compounds reduce the rolling resistance by up to 35 % and thus save up to 8 % fuel and CO₂ emissions. Additionally, it improves the wet grip and thus significantly shortens the breaking distance.
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.
Protective coatings
Nourybond® adhesion promoters are essential in automotive sealant, underbody, and anti-chip primer formulations, providing unique rheological properties and improved adhesion to electro-deposition primers.
VESTAGON® protects powder coated rims, assembly parts and automotive trim from chemical attacks e.g. from acid rain and brake fluids. Furthermore, they have to be UV and stone chip resistant.
Clear coats based on VESTANAT® EP-M family combine the flexibility and ease-of-use of a PU coating with a glass-like hardness. This results in unprecedented scratch- and chemical resistance.
VESTANAT® H12MDI makes car wrapping foils chemical resistant against aggressive agents like acid rain, bird droppings, and gritting salt on the roads.
Interior and seats
ORTEGOL® LA 3 is a second-generation aldehyde scavenger which reduces formaldehyde and acetaldehyde emissions in automotive molded foams, helping to reduce the “new car smell” without compromising the quality of the PU application.
TEGOSTAB® offers a large variety of different low odor surfactants for use in all major PU applications (e.g., rigid, flexible slabstock, molded and high-density foams), some with very low volatile organic compounds (VOC).
The surface of trims, panels and operational controls made with the microcrystalline TROGAMID® do withstand not only UV light, deep and high temperatures, but also contact to aggressive sweat, skin oil, suntan lotion and other cosmetics.
