New polymer for high-heat EV battery module insulation

Solvay announced a new high-heat and flame retardant grade in the company’s Xydar® liquid crystal polymers (LCP) portfolio, which is designed to meet critical safety demands in EV battery components. The new Xydar® LCP G-330 HH material addresses challenging thermal and insulation requirements and is targeted particularly at battery module plates of EV models operating with higher voltage systems.
Xydar® LCP G-330 HH is a glass-filled LCP for injection molding capable of retaining its electrical insulation upon exposure to 400°C for 30 minutes. Xydar® LCP is an inherently flame retardant polymer, without the use of halogen or bromine additives. In addition, it offers exceptional flowability and helps battery designers achieve thinner parts than possible with incumbent battery module insulation materials. It has been successfully tested with plates molded in typical dimensions of 100 x 150 x 0.5 mm.
Xydar® LCP has a proven fit in many electrical and electronic as well as coating applications. Besides automotive lighting components, sensors, solenoids and connectors, advanced examples in e-mobility include thin-wall slot liners used in the rotor design of an electric drive traction motor.
