PE-F6004 – Polyurethane Flame Retardant Encapsulation Foam
PE-F6004 is two-component flame retardant, low density polyurethane foam material designed for potting and encapsulation of battery cell in EV battery modules or other easily flamable applicatoions. PE-F6004 offers design engineer the ability to increase the power density of their modules while ensuring safety and protection from thermal propagation. The ultra lightweight nature of the PE-F6004 minimizes the weight impact to the 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 environment impacts.
