General Motors’ use of DuPont™ Zytel® PLUS nylon for its Ecotec 2.0-liter turbo powering Cadillac CTS vehicles captured the ‘Most Innovative Use of Plastics” Award in the Materials category from the Society of Plastics Engineers (SPE) Automotive Division. The award-winning engine-appearance and acoustic cover is molded by Camoplast Polymer Solutions, Richmond, Quebec, Canada.
Ford, Fiat and Toyota walked away with innovation awards at the 2011 Society of Plastics Engineers “Most Innovative Use of Plastics Awards” event for components that use two renewably sourced DuPont materials — DuPont™ Zytel® RS nylon and DuPont™ Sorona® EP polymer — and one component using DuPont™ Hytrel® TPC-ET.
For maximum protection against fires, the body must be covered as completely as possible with flame-resistant protective clothing. This requires long pants and long sleeves, making for hot work in warm and humid climates. Understandably, industrial workers may be concerned about potential heat stress when wearing protective apparel. Learn more about the factors that can lead to heat stress, and how DuPont brands can help offer comfort and protection in protective garments.
DuPont is working with our auto industry collaborators to help them develop the next generation of sustainable mobility solutions. Together, we’re helping reduce dependence on fossil fuels and lower greenhouse gas emissions to help manage the environmental impact associated with the world’s increasing demand for automotive mobility.
Bio-based products are a critical component of DuPont’s efforts to reduce dependence on fossil fuels. When it comes to bio-based products, DuPont science is innovating across the entire development chain, from seeds and feedstocks through proprietary fermentation and chemical processes to the final high-performance, economically efficient products our customers demand.
Many of today’s vehicle system environments are like a pressure cooker of aggressive chemicals. Very few materials have the right combination of characteristics to withstand that kind of severe treatment. DuPont is at the forefront of the development of the latest generation of high performance materials.
DuPont™ Vamac® ethylene acrylic elastomer (AEM) has been chosen by Huber + Suhner AG, Switzerland, a leading supplier of automotive cable systems, as insulation for battery cables supplied to Fiat, Ford, Jaguar, GM/Holden and Renault, and also as screened insulation cables for hybrid prototypes and the fully electric Tesla Roadster.
DuPont Automotive has the broadest range of high-performance materials for hybrid and electric vehicles, which play an ever more important role in helping to reduce carbon emissions and dependence on petroleum. With its deep application expertise, DuPont helps automakers quickly develop more efficient, safer, lighter vehicles.
DuPont™ Opteon™ yf (HFO-1234yf) is a new refrigerant with a GWP of 4, which exceeds the EU MAC Directive by 97 percent. Developed in partnership with Honeywell, Opteon™ yf refrigerant is an energy-efficient, safe and easy-to-implement solution, delivering environmental, industry and consumer benefits.
DuPont renewably sourced automotive interior materials help automakers support sustainability efforts without sacrificing performance. Materials include DuPont™ Sorona® fiber for carpeting and seat upholstery, DuPont™ Sorona® EP thermoplastic polymer for injection molding applications such as vent louvers, and DuPont™ Hytrel® RS thermoplastic elastomer for airbag systems.
The plant-derived DuPont™ Zytel® RS 610 nylon resin that debuts on a new automotive radiator end tank from DENSO Corp. illustrates the benefits of close collaboration throughout the value chain and marks the first use of DuPont renewably-sourced plastic in mechanical components exposed to the hot, chemically aggressive underhood environment.
Recent testing of DuPont™ Vamac® ultra ethylene acrylic elastomers (AEM) and new grades of DuPont™ Zytel® nylon resins and semi aromatic DuPont™ Zytel® HTN in aggressive AdBlue* aqueous urea solution has demonstrated the effectiveness of these products for selective catalytic reduction (SCR) systems used to reduce NOx emissions from diesel engines.
Today’s automotive design professionals must resolve competing needs: greater fuel economy, CO2 emissions reduction, lower costs, and improved performance, safety, and comfort. DuPont’s integrated global application development teams focus on eight automotive themes to guide the development of innovative, science-driven solutions.
Vehicle weight reduction is a major challenge. While plastics are inherently lighter than metals, lightweighting requires more than direct material substitution. DuPont predictive engineering and design teams work with customers, using insight and high-performance DuPont materials to redesign for lower weight, often integrating functions to cut costs at the same time.
Engine downsizing, lightweighting, turbocharging, direct injection, and exhaust gas recirculation are all responses to the drive for greater fuel economy, higher engine efficiency and lower CO2 emissions. But these advances come at a price. They generate more heat, and involve more aggressive gases, fluids, and acidic gas/air mixtures, often under high pressure.
