We offer innovative fire-resistant material solutions to produce battery enclosures. The phenolic product has been designed for traditional sheet molding compound processes and does not require any fillers or intumescent coatings to achieve its fire-retardant performance. The epoxy product brings structural integrity in combination with continuous fiber and can be formulated with fillers to meet fire safety requirements. Both product solutions addresses increasing concerns on the fire safety risks of battery packs having increasing energy density.
