E-mobility flammability standards
Freudenberg-NOK Sealing technologies is applying its aerospace heat-resistant materials portfolio to address battery housing material standards for electric vehicles (EVs). Scientists at company laboratories in Plymouth, Michigan, worked with engineers at the company’s aerospace material and component manufacturing facility in Ontario, Canada, to formulate a new silicone-based material that complies with an international flammability standard for EVs in China — materials must immediately self-extinguish after being exposed to a flame.
“We were able to significantly shorten the product development cycle for our customer by leveraging our aerospace portfolio and expertise,” says Todd Blair, Freudenberg-NOK business development manager in Tillsonburg, Ontario. “As E-mobility vehicle producers introduce more powerful, quick-charging, and longer-life batteries, heat and temperature are going to become bigger issues. The aerospace industry has a head start in dealing with these kinds of challenges, and we have more material expertise than most in developing solutions that address them.”
Freudenberg’s material experts have also begun formulating advanced fireproof materials that exceed current customer requests. Currently in advanced field testing, new materials contain a fire when exposed to a flame and protect the battery and nearby components to temperatures hotter than 2,000°F. https://www.fst.com
