Pyroflow

Pyroflow - Passive:
Mineral-based fire suppression agent for metal fires and Lithium-ion batteries.
Used for Transport & storage applications
By using Firechief PyroFlow as a packaging media, in the event of a battery fire Firechief PyroFlow melts to form glass, caused by the high temperatures as released by such an incident. In the process, the granules absorb a lot of heat as they melt, thus cooling the fire, and at the same time forming an impermeable shell around the fire load encapsulating it from further reaction.

Pyroflow - Active: 
Mineral-based fire fighting agent for metal fires and Lithium-ion batteries
Used on active Fires.
By covering the fire load with Firechief PyroFlow, oxygen is separated from the combustible material. Firechief PyroFlow melts to form glass caused by the high temperatures as released by such an incident. In the process, the granules absorb a lot of heat as they melt, thus cooling the fire, and at the same time forming an impermeable shell around the fire load, encapsulating it from further reaction.
Can be used in both "Class D fires and for Lithium-Ion fires.

Please note there is no expiry date for either the Passive or Active, providing they are stored as required and there is no damage to to bags.
