Polyurethane Foam Encapsulant Protects and Lightens EVs
A two-component, ultra-low density, flame-retardant polyurethane foam is designed for potting and encapsulating lithium-ion battery cells in EV battery modules.
H.B. Fuller realized that if it formulated a product that was lightweight, low cost, and had NVH properties, it would fit the needs of today’s electric vehicle (EV) battery manufacturers. Creating an encapsulant that was fire retardant was also of upmost importance to H.B. Fuller to protect the battery from potential fire propagation. With all of this in mind, the company developed a product in 2016 that was years ahead of its time and loaded with future potential.
Created to provide NVH properties and damp vibration in EV battery pack modules, EV Protect 4006 is a two-component, ultra-low density, flame-retardant polyurethane foam, designed for potting and encapsulating lithium-ion battery cells in EV battery modules. This innovative material is easily integrated into battery module designs by filling voids, expanding five-fold, encapsulating all battery cells, and insulating the individual cells from each other.
