Evonik’s debut at the Auto Shanghai 2011
For the first time, Evonik Industries will demonstrate a wide range of applications for cars at the 14th Shanghai International Automobile Industry Exhibition (Auto Shanghai 2011) from April 21 to 28 in Shanghai, China.
The theme of Auto Shanghai 2011, “Innovation for Tomorrow”, reflects that low-carbon, green economy and sustainable development will become trends of the high-aiming Chinese automotive industry. This concept fits perfectly with Evonik’s four key innovation fields in the automotive industry, namely Lightweight Design, Fuel Savings and Emission Reduction, Surface Technologies, and Lighting Technologies.
China's overall auto sales rose 32.4% to 18.06 million units in 2010. The automotive industry is one of the most important and high growing markets for Evonik. As a global leader of specialty chemicals, Evonik is committed to develop our products and solution catering to the new demands of the automotive industry.
Lightweight design in the spotlight
As the largest auto manufacturer and market, China has to tackle the challenges from energy shortage and environmental pollution at the same time. Responsible individuals and organizations are thinking how to improve the living standard in a more sustainable way, such as driving our cars of higher energy efficiency while achieving lower carbon emission.
In order to capture the opportunities in an energy efficient automotive market, Evonik has set up the Lightweight Design Automotive project in China last October. “Our goal is to speed up the development and application of Evonik’s innovative lightweight materials for the Chinese Automotive Industry,” said Xu Hang, Project Head of Lightweight Design.
Evonik’s products have been successfully used in the lightweight design of vehicles, such as ROHACELL® foam core for sandwich structure of hatch back, PLEXIGLAS® glazing for side windows, VESTAMELT® adhesion promoter for structural hybrid parts, etc. ROHACELL® foam core covered with fiber reinforced materials can lower the weight of a car body significantly by 60 percent compared to steel parts. Diamines marketed under the trade name VESTAMIN® are indispensable components in high performance fiber reinforced epoxy parts imparting high strength, light weight sandwich as well as monolithic composite structures. PLEXIGLAS® glazing by Evonik offers a weight savings potential for car screens by 40-50 percent, but still has excellent performance in acoustics, UV resistance and weathering. Structural hybrid parts incorporating VESTAMELT® adhesion promoter can reduce material consumption by about 25 percent but as strong as before or even higher in bond forces between steel and polymer.
Innovative and eco-friendly technologies
Global warming, growing oil prices and restricted crude oil resources claim new technologies which reduce the fuel consumption of vehicles. And Evonik provides intelligent answers for tires, tubing systems and power train.
For example, the use of silane additive Si 363® allows the tire’s rolling resistance to be reduced by about 10 percent compared with conventional tires, which leads to fuel savings of 3 to 8 percent. The product has already been applied in Aspire Low Rolling Resistance tire. Fuel lines made of Evonik’s special plastics are, by virtue of their durable properties, thinner and lighter and thus more easily formable than common systems of metal or elastomers. They are also able to lower weight considerably. Under the VISCOPLEX® trademark, Evonik RohMax develops high-performance components added to lubricants to make them more efficient and reliable, as well as to prolong the service life of engines and gears (transmission systems).
In addition, Evonik will also display a “Heat BuildUp” box with illumination, which demonstrates the concept of PLEXIGLAS® Heatstop® - a specialty molding compound. It is particularly suitable for dark-coloured exterior applications; its special formulation enables it to reflect solar heat radiation. Car roofs made from PLEXIGLAS® Heatstop® “with cool touch effect” show up to 22 percent less heat build-up than components made from conventional materials. They therefore reduce the temperature inside the vehicle by an average of 5 °C, related to the solar radiation on a regular summer’s day in Central Europe. Light-stable polyurethanes based on VESTANAT di- and polyisocyanates find applications in premium quality automotive interior trim like e.g. skins for I-panels, domings for decorative parts and leather coatings as well as soft-feel-coatings.
Developing trends for cars of tomorrow
Vehicles of today offer a unique combination of advanced technologies and aesthetic, functionality and environmental awareness. That’s where high grade coatings are applied - specifically developed for the automotive industry. Moreover, a good illumination is an enormous factor to enhance safety. Improved vision for the driver and improved visibility of the vehicle are both important aspects of safety. Therefore, surface and lighting technologies will be the next further development fields for Evonik in the automotive industry.
Evonik provides plastics for both the interior and exterior parts of automobile, while they do not only feature excellent UV resistance and weatherability, but also lower fuel consumption and thus CO2 emissions.
PLEXIMID® TT70 gives headlamp lens and light guide manufacturers a material that can cope with the high heat loads and permits dynamic styling at the same time. PLEXIMID®, a grade of polymethylmethacrylimide (PMMI), is a further development of PLEXIGLAS® PMMA product and shows similarly high transparency and resistance to weathering and UV light as the other popular PMMA products from Evonik.
High speed for innovations: the Automotive Industry Team of Evonik
The Automotive Industry Team (AIT) of Evonik was founded in 2004 as a cut surface to the Original Equipment Manufacturers. This team bundles the competencies of four business units from Evonik as development partner for new technologies. The China AIT is established in 2006, with aims to provide localized and customized solutions for local OEMs, catering to the market trends and needs of Chinese automotive industry. Leverage on this platform, we are determined to push on new material concepts in the automotive industries and boost the necessary innovation speed.
