They focus on the development areas of lightweight design, fuel savings and emission reduction, as well as lighting and surface technologies. Innovative technologies from Evonik play an important role in reducing fuel consumption, such as oil additives to improve the efficiency of the engine and transmission, products for tires with low rolling resistance, enhancements of lithium-ion batteries for full electric and hybrid vehicles and lightweight design concepts to reduce overall vehicle weight. Triacetone amine and its derivatives are used as elementary precursors for highly-efficient UV stabilizers that enable plastics to be used in automobiles.
In the engine compartment, cast metal parts can be impregnated with the help of monomers from Evonik in order to improve mechanical stability and, ultimately, prolong the life of the materials.
Other key technologies for vehicles are high gloss surfaces with enhanced abrasion resistance as well as plastics for high-quality, permanent colored body hang-on parts, polymer materials used in decorative panels for the automobile interior and materials that minimize abrasion and prevent dirt adhering. When it comes to lighting systems inside and outside the vehicle, PMMA molding compounds are used as durable covers and as fiber optics for tail and signal lights or in combination with LED technology for contour lighting and ambient lighting in the vehicle interior.
Transparent PMMA is up to 40 to 50 percent lighter than conventional glass when used as automobile glazing for side and rear windows and sunroofs, which opens up many new design possibilities.
For glass bonding and when used in adhesive protective masses and insulation compounds, the plasticizers from Evonik ensure a combination of flexibility and adhesion. In addition, fumed silica improves the rheological and mechanical properties of windshield adhesives and organofunctional silanes are used as adhesion promoter in windshield adhesives. In the production of state-of-the-art vehicle body parts there are high demands to reduce weight and guarantee stability. With hardener components for epoxy resin-based carbon fiber composites, Evonik makes an important contribution towards the future of lightweight automotive construction.
