Fire protection/extinguishing agent expanded glass granulate, for lithium batteries/rechargeable lithium batteries, 55 l sack, 12.5 kg. Supplied = assembled. Contents = 55 l. Material = recycled glass. Temperature resistance = up to +1000 °C. Material properties = non-flammable. Product type = accessories for rechargeable battery storage/transport containers. Fire protection/extinguishing agent in the event of ignition of lithium batteries (thermal runaway) Absorbent in the event of electrolyte escape, filters burnt gas. Temperature resistant to more than 1000 °C, not conductive, non flammable, good thermal insulation. Reusable, environmentally friendly. Expanded glass granulate is foamed, recycled glass - 100% mineral. Non flammable (certified non flammability, building material class A1, DIN 4102) Extinguishing effect due to suffocation and isolation of the source of the fire. Melts at high temperatures - absorbs heats in the form of melt energy. Creates a shield around the battery housing - prevents a reaction with oxygen.
