Sustainable Automotive Fuel System Technologies
Permeation rates and material performance in conventional and biofuels are critical to meeting emissions regulations and reducing fossil fuel dependence. Our expertise in fuel storage and delivery systems and biofuel knowledge help automakers meet these challenges.
Our materials for automotive fuel system technologies and components offer long-life performance despite exposure to aggressive fuels, helping automakers cost-effectively meet emissions regulations and increase fuel efficiency. Our biofuels technologies help reduce dependence on fossil fuels.
Fuel System Design: DuPont offers the industry’s broadest portfolio of materials for fuel system components, including elastomers, fluoropolymers, fluoroelastomers and thermoplastics. These materials free engineers from metal’s design constraints while reducing weight and vapor emissions.
Sustainability: DuPont materials cost-effectively reduce permeation and resist attack from conventional fuels and aggressive biofuels to help meet emissions regulations, reduce fossil fuel dependence and improve reliability.
Biofuels: We have a joint venture with BP to develop biobutanol, which has a 25% higher energy density than ethanol, can be blended into conventional gasoline at higher concentrations, and can be used in existing vehicles. We are also advancing enzyme technologies to help enable cost-effective ethanol.
Alternative Drive: DuPont’s expertise in fundamental material science and electrochemistry helps the industry develop fuel cells.

DuPont™ Vamac® ethylene acrylic elastomer products thrive in harsh environments, performing in turbocharger hoses, oil cooler hoses, seals and gaskets. Vamac® elastomers can be fashioned into cured compounds with superb low-temperature resistance, high-temperature durability, and resistance to auto fluids, such as transmission fluid and engine oils.
Zytel® nylon resin is the most versatile of plastics - easy to process, easy to modify, and environmentally responsible in production and in reuse. It's tough, light and surprisingly resilient in hot, chemically aggressive and humid environments. DuPont™ Zytel® HTN high-performance polyamide bridges the performance gap between conventional engineering resins and high-end specialty polymers.
Crastin® PBT Thermoplastic Polyester Resin
DuPont™ Crastin® PBT thermoplastic polyester resins deliver superior electrical insulation performance, plus heat resistance and physical toughness – an ideal combination for numerous applications.
Teflon® Fluoropolymer Resins
A staple in kitchens since the 1960’s, DuPont™ Teflon® nonstick coating systems make life easier. Did you know the Teflon® brand goes far beyond cookware? It is also found across a broad range of consumer and industrial applications and processing techniques.
Tefzel® ETFE Fluoropolymer Resin
DuPont™ Tefzel® ETFE fluoropolymer resin is a modified ethylene-tetrafluoroethylene fluoropolymer available as pellets, or as powder for rotational molding. Tefzel® ETFE resin combines mechanical toughness with an outstanding chemical inertness that approaches that of DuPont™ Teflon® fluoropolymer resins.
