PNS-F is effective at extinguishing gasoline fires and has excellent burnback capability
Over the past two years, we have discovered a new class of fire extinguishing agents which are chemically related to PNS but which have both fire extinguishing and foaming properties. We call this new class of compounds PNS-F. When subjected to flames or intense heat, they convert to intumescent foamy char and have been found to be effective at extinguishing fuel fires.
