H.B. Fuller EV Protect 4006 SFR is a liquid-applied, two-component flame-retardant, low-density polyurethane foam material engineered for potting and encapsulating battery cells in electric vehicle (EV) battery modules. It allows engineers to increase the power density of their modules while enhancing safety and protection from thermal propagation. Its ultra-lightweight nature minimizes weight impact on battery modules. Additionally, it offers noise, vibration, and harshness benefits to the battery system by unitizing the battery module and absorbing external environmental impacts.
