Glass-filled polymer for EV battery modules

Solvay has launched a new polymer grade in its Xydar range of liquid crystal polymers (LCPs).

The new material is reportedly high-heat and flame retardant, making it suitable for use in electric vehicles (EVs).

“As automakers are moving from 400V to 800V on next-generation electric vehicles, new regulations in Europe, China, the United States and other countries are increasing the demand on battery components to withstand temperatures from 300°C to 1000°C for an extended window of up to 15 minutes,” said Brian Baleno, head of marketing. “Appropriate materials are expected to retain a level of electrical insulation protection that will provide sufficient time for passengers to exit the vehicle in a thermal runaway event.”

Xydar LCP G-330 HH can be processed using injection molding and retains its electrical insulation upon exposure to 400°C for 30 minutes, the company said. It reportedly has improved flowability making it easier to produce thinner parts. It has been successfully tested with plates molded in dimensions of 100 x 150 x 0.5 mm.
