Freudenberg SE (Freudenberg) announced that Freudenberg Sealing Technologies has revealed a new thermoplastic called Quantix ULTRA that helps improve fire protection in EVs.
The material, processed through injection molding, can withstand extreme temperatures of up to 1,200 degrees Celsius without melting or igniting. With a glass transition temperature that is 53 Kelvin higher, it retains its rigidity and flame protection over a longer period.
It exhibits elastic behavior similar to elastomers and has lower density than metallic materials, which is ideal for lightweight construction in EVs.
The first series application is now underway, as a flame protection barrier for cooling system parts in an EV’s lithium-ion battery. As of February 2024, it will be used for the first time by a car manufacturer in series production vehicles.
In addition, this material can be used in other areas, such as enclosures for power supply units, media-carrying lines, cable insulation, battery housing covers, and components for electric motors. (From a press release dated January 17, 2024)
