Protecting electric car batteries against fire is crucial to the success of these vehicles. There is particular concern about thermal runaway. A new Quantix® ULTRA material class from Freudenberg Sealing Technologies significantly improves fire protection in electric vehicle drives: The thermoplastics made from this material can withstand temperatures of up to 1,200 degrees Celsius. The ability to process the material in injection molding makes it both versatile and economical. Given that today’s vehicles call for lightweight construction, its lower density compared to metallic materials is an additional advantage.
