Firechief® PyroFlow™ Passive Fire Suppression Granules – 12kg Paper Bag (PFP12)
A powerful passive fire protection solution, the 12kg Firechief® PyroFlow™ bag is perfect for encapsulating lithium battery sources in packaging. Its mineral composition ensures non-combustibility, while its pore structure offers advanced heat absorption and encapsulation. Ideal for use in specialist containers and battery transport units.



Fire Protection Through Passive Encapsulation
The Firechief® PyroFlow™ Passive Fire Suppression Granules offer a forward-thinking solution for managing lithium-ion battery risks in transport and storage environments. Crafted from 100% mineral-based expanded glass granulate, these eco-friendly granules are non-toxic, thermally stable, and designed to both prevent and suppress fires.
When exposed to extreme heat, the granules melt into glass, absorbing heat and forming a containment shell around the battery fire source. This isolates and smothers the fire, reducing the risk of thermal propagation, chemical release, and secondary ignitions. These characteristics make it an ideal packaging medium in logistics, warehousing, and battery storage.
