DuPont, Chery Automobile Showcase Lightweighting Solutions


Collaboration is Essential in Bringing Science-Based, Advanced-Material
Solutions to Market

WUHU, China, Nov. 27, 2012 – The Chery taxi featured in a DuPont mini-documentary illustrating the benefits of lightweighting, uses several DuPont advanced materials, including DuPont™ Zytel® nylon resin and DuPont™ Vamac® ethylene acrylic elastomer in components ranging from air-intake manifold and cylinder head cover to air ducts.

Together the components account for about 30-40 percent decrease in component weight compared with their metal counterpart, generating a significant increase in fuel economy and reduction in CO2 emissions.

“The need to continue the drive to improve the sustainability of vehicles to meet mobility needs continues to drive innovation in the automotive industry,” said James Hay, regional director, Asia Pacific, DuPont Performance Polymers. “Working closely with customers helps ensure we develop advanced material solutions that deliver more sustainable solutions without compromising performance, safety or cost.”

Less Means More

The DuPont video features Cao Tieniu, who drives a Chery taxi in Wuhu, China. “Compared to some cars, it uses less fuel,” he said. “For those of us who drive taxis, it increases our profits.”  For Tieniu, that translates to more time with his family.

“Lightweighting technology is a very important component in the process of fuel efficiency,” said Chen Anning, vice president, Chery Automobile.  “There has been a lot of cooperation between DuPont and Chery.”

Chery has a long history with DuPont working with the teams in the China R&D center and around the world to develop lightweight components throughout the vehicles, but especially in engine components and systems. “Components surrounding the engine need to be resistant to high temperatures,” said Charlie Huang, business director, DuPont Performance Polymers, Greater China. “This is where engineering polymers can demonstrate their power.” Currently, the business is collaborating with Chery on developing plastic oil pans for several new engines which have high market potentials.

“Together we established the Chery-DuPont Joint Laboratory of New Materials Technology and Application Development in August 2010.  It is an important platform for sharing new technologies and products and demonstrating development results,” said Anning.  “The collaboration focuses on light weighting, new energy vehicles, interior and exterior accessories, advanced coating process, etc.  Chery is committed to the development of hybrid vehicles, electric vehicles, new environmentally friendly materials, and new processes.”

DuPont – one of the first companies to publicly establish environmental goals more than 20 years ago – has broadened its sustainability commitments beyond internal footprint reduction to include market-driven targets for both revenue and research and development investment. The goals are tied directly to business growth, specifically to the development of safer and environmentally improved new products for key global markets.

DuPont offers more than 100 materials and product families for the global automotive industry. Through its global application development network, DuPont Automotive is committed to collaborating with customers throughout the value chain to develop new products, materials, components and systems that help reduce dependence on fossil fuels and protect people and the environment.
