EV Protect 4006 SFR is a liquid applied, two-component flame retardant, low density polyurethane foam material designed for potting and encapsulation of battery cell in EV battery modules. EV Protect 4006 SFR offers battery design engineers the ability to increase the power density of their modules while ensuring safety and protection from thermal propagation. The ultra lightweight
nature of the EV Protect 4006 SFR minimizes the weight impact to the battery modules. The semi-structural properties of the material also provide noise, vibration, and harshness benefits to the battery system by unitizing the battery module and absorbing external environmental impacts.
