PyroFlow Passive Fire Suppression Granules – 12kg Paper Bag

Reduce the risks associated with lithium-ion batteries and metal fires using PyroFlow Passive Fire Suppression Granules (PFP12), a mineral-based, non-toxic and eco-friendly suppression agent supplied in a convenient 12kg paper bag. Made from expanded glass granulate with lightweight, porous spheres, PyroFlow is 100% mineral-based and non-combustible, making it a practical choice for both preventative protection and incident response where lithium batteries are present.

PyroFlow can be used as a thermally stable packaging filler in specialist or fireproof containers. In a thermal runaway event, the granules absorb heat and melt to form a glass-like, impermeable shell, helping to encapsulate the fire load and limit further reaction. It also binds liquids and filters gases, supporting cleaner, more controlled containment as part of a wider fire risk mitigation strategy.

Key benefits:

• Mineral-based fire suppression agent for metal fires and lithium-ion batteries
• Non-toxic, eco-friendly and non-combustible expanded glass granulate
• Can be used as thermally stable packaging media when Li-ion batteries are present
• Helps smother, suppress and encapsulate batteries during thermal runaway
• Effectively binds liquids and filters gases
• Coarse granulate 1–4mm for practical packing and coverage.

Typical use (storage/packaging mitigation):

• Recommended for use with fireproof or specialist containers
• Position batteries centrally to ensure a sufficient layer of granules on all sides
• Follow a suitable fire risk assessment and use appropriate PPE
