EV Protect 4006
Fire-Retardant Encapsulation Foam | H.B. Fuller
EV Protect 4006
PRODUCT DESCRIPTION:
EV Protect 4006 is a two-component flame retardant, low-density polyurethane foam. These materials are designed for potting and encapsulation of cylindrical cells in EV battery modules to help prevent thermal runaway/propagation events and reduce shock and vibration. They can also be used in other potting applications where low density and flame retardancy is desired. These materials require the proper mix and dispensing equipment to ensure a uniform cell structure.
