INFORMATION & IDEAS
DuPont has been working on PA12 alternatives and has established global development and supply teams to work with customers to quickly qualify alternative materials for use in many automotive and industrial components.
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.
A quick guide to elastomer properties and application development assistance.
DuPont offers a range of tested heat resistant elastomers for applications from automotive engines to oil and gas production equipment.
DuPont has a portfolio of chemical resistant elastomers and thermoplastics to match a broad spectrum of challenges – from aggressive automotive fuels to custom industrial equipment.
DuPont was the first company to commercialize a PA1010 polymer for the automotive market. Zytel® RSLC 1610 is a PA1010 specifically formulated to provide better thermal properties and chemical resistance to biodiesel fuel, compared with the materials it replaced.
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.
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.
DuPont collaborates with customers worldwide to develop innovative metal replacement applications to make cars, planes and other equipment more fuel- and cost-efficient.
Kalrez® parts last longer and seal more effectively than other elastomers due to their exceptional heat resistance. Even after long-term exposure up to 327°C, they retain elasticity and recovery properties better than other high temperature elastomers.
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.
DuPont offers a range of materials designed to resist high temperatures and aggressive fuels in automotive fuel hoses.
Fuel Line Made of Renewably Sourced DuPont™ Zytel® Nylon Provides Long-Term Resistance to Biodiesel
The auto industry’s current materials portfolio will need to be augmented to meet new 2025 fuel economy standards, according to a recent WardsAuto and DuPont Automotive survey in July of 2011. Respondents also said materials used in power train vehicle systems will change the most.
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.
With global biofuel use expected to double by 2015, DuPont has developed a new generation of heat-, pressure- and chemical-resistant elastomers for fuel system components that can withstand aggressive fuel environments.
