Lanxess’ FR, Glass-Reinforced Nylon 6 Selected for Lower Weight EV Battery Housings
A Durethan nylon 6 grade from Lanxess applied to a series production of Korean carmaker
New battery module housing for electric vehicles (EVs) featuring a halogen-free, flame-retardant and glass-fiber-reinforced nylon 6 from Lanxess has been adopted to series production of EV models launched this year by Korean auto parts specialist Infac.
The battery housing uses Durethan BKV30FN04 to satisfy stringent mechanical and chemical property requirements for today’s EV components. The material is characterized by its excellent flame-retardant and electrical properties, excellent processability, and its enabling of integration of complex functions required for housing components, resulting in a smaller number of parts and a simplified assembly process as well as lighter weight.
Said Milan Vignjevic, head of Lanxess’ High Performance Materials (HPM) business unit in Asia-Pacific, “Success in mass production of battery housing demonstrates Lanxess’ Durethan’s excellence in EV batteries, in which technology and safety are of utmost importance. Our high-performance plastics will make a significant contribution to the EV and battery markets.”
For the battery module housing shock absorption and thermal management are critical in order to protect the battery from external shock. Durethan BKV30FN04 reportedly is not only mechanically robust, but also boasts high-voltage insulation, resistant to up to 800 V and effectively blocking high-voltage current. With strong flame-retardant properties, it prevents or delays flames from spreading in case of a fire, and the glass-fiber reinforced resin grade’s durability to mechanical loads is superior to unfilled nylon 6. Moreover, it is said to maintains excellent strength and stiffness when in contact with electrolyte or cooling media, and has chemical resistance to suppress chemically-induced damage.
Since its establishment in 1969, Infax has been operating 17 sites in Korea, the United States, Mexico, China, Czech Republic, India, and Vietnam, supplying auto parts to leading global automakers. With its continuous R&D efforts in auto parts ranging from chassis, electronic and driving parts to eco-friendly cars and future intelligent cars, the company is solidifying its position as a global OEM parts supplier
