INFORMATION & IDEAS
Zytel® PLUS nylon has the ability to retain properties after heat aging or long term exposure to hot oil and hot water, allows longer part service time, better reliability, and invites more opportunity to replace costly metals or specialty polymers to reduce part cost and lower mass.
Technology that boosts efficiency, while reducing the size of gas and diesel engines, is the main route to lower emissions and improved fuel economy.
PPA materials offer great resistance to hydrolysis and moisture and they are relied upon for cost effective applications such as water inlets/outlets, thermostat housings, water pumps and impellers
DuPont offers a wide range of heat resistant plastics to replace metal, ceramics and other polymers in uses from automotive engines to oil and gas production.
DuPont supports efforts/initiatives to improve sustainability in the automotive industry with high performance and renewably-sourced polymers that can help increase fuel efficiency while reducing energy loss, emissions and costs.
DuPont plastics applications for the powertrain help automakers reduce weight and integrate parts, which boosts automotive performance and delivers productivity and cost savings.
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.
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.
A newly-developed two-component air duct blow-molded using stiff yet elastic DuPont™ Hytrel® TPC/ET, connects the intercooler and throttle body of the three liter, six cylinder twin-turbo engine from BMW.
DuPont high-performance materials for turbochargers and emissions systems can withstand the high heat and corrosive fluids in downsized engines, and reduce friction and improve wear for components.
