DuPont reports its lightweight materials extend EV driving range by 30%
“Especially in EV applications, these high temperature and chemically resistant products and electrical insulation materials contribute to increased EV system reliability and performance under severe conditions such as wide ranging temperatures and high voltage,” said Tomoyuki Shinkai, Operating Officer, Vehicle Development Co-ordination Division General Manager, SIM-Drive Corp.
As stated in its release, DuPont high-performance plastics such as DuPont Zytel HTN PPA in the in-wheel motor and DuPont Kapton polyimide film in indicator lighting helped SIM-Drive keep weight lower than EVs on the road today. DuPont Zytel HTN used in key in-wheel motor bobbins is stronger, lighter and more cost effective than the PPS it replaces. Kapton, known for use in high-reliability applications from Mars Rover to mobile devices, replaces the need for a circuit board, shaving 80% of the weight from the lighting component.
“This project shows how light weight, high-performance materials such as Zytel HTN PPA can take extremes, allowing designers to bring innovation to electric and hybrid electric vehicles without adding weight associated with metal,” said James Hay, Regional Director, DuPont Performance Polymers, Asia Pacific.
Meanwhile, bio-based DuPont Sorona polymer improves the environmental footprint and is used in interior applications. SIM-WIL also uses DuPont coatings and DuPont Corian for refined touchpoints.
“Innovations that help reduce dependence on fossil fuels play a critical role in the future of the automotive industry,” said DuPont Kabushiki Kaisha (DKK) President Minoru Amoh. “The power is both in the technology and the collaborative business model used to develop the prototype.”
