LANXESS working on new materials for lighter, fuel-efficient cars

In order to offer solutions for sustainable, resource and climate-friendly mobility, the German specialty chemicals company LANXESS is developing materials for cars of the future, according a company press release. “Chemical materials are the key to making cars lighter and more efficient. That is why our company is working systematically to develop new high-tech thermoplastic systems for lightweight construction and high-performance rubber products for low-rolling-resistance and thus fuel-saving tyres,” said Dr Werner Breuers, member of the LANXESS Board of Management in advance of the 65th International Motor Show (IAA) in Frankfurt, Germany.
 
LANXESS has been offering solutions for the development of lightweight automotives. “The weight of a vehicle can be reduced immediately by 50 kg solely through the use of our production-proven, high-performance thermoplastics Durethan, Pocan and TEPEX in a wide variety of applications. The results are fuel savings of up to 4 percent and a reduction in CO2 emissions of up to 0.5 kilograms per 100 kilometers,” Breuers added. One example of a LANXESS innovation in the field of lightweight construction is a new polyamide 6 Durethan for use as a fuel tank inliner for natural gas-powered vehicles. According to Breuers, “The plastic tanks with this inliner weigh only one-fourth as much as an all-steel tank, reducing vehicle weight by as much as 7 percent.”
 
TEPEX continuous fiber-reinforced thermoplastic composites from Bond-Laminates, a company of the LANXESS group, have a bright future in lightweight construction. In many cases, TEPEX is a high-performance and cost-effective alternative to carbon fiber-reinforced thermoset lightweight materials. Used in place of sheet metal, it significantly improves the lightweight construction potential of plastic-metal hybrid technology – by roughly 10 percent compared with hybrid technology using aluminum. Potential applications where TEPEX hybrid technology can be implemented directly in volume production include front ends, vehicle seats, seat cross-members, pedals and airbag housings.
 
Another example of LANXESS’ expertise when it comes to ‘green’ mobility are high-performance rubber grades for low-rolling-resistance tires. “Our rubber products reduce the tires’ rolling resistance, which in turn reduces fuel consumption by 5 to 7 percent and thus also reduces CO2 emissions. These green tires already make possible significant contributions to climate protection with existing vehicles,” Breuers said. LANXESS has presented a concept tyre developed internally on the basis of the company’s rubber products and additives that was the first of its kind anywhere in the world to receive an AA rating according to the EU’s compulsory tyre labeling system.
