Petroseal 3%

Petroseal 3% is a superior quality Film-Forming FluoroProtein (FFFP) fire fighting foam concentrate for extinguishing and securing flammable hydrocarbon liquid fires.

Its unique formulation is based on advanced protein foam technology. The protein base material provides a tough cohesive foam blanket with high resistance to heat that provides the same post-fire security as a top quality FluoroProtein (FP). Fluorochemical surface active agents combined with the protein base produce a vapor sealing aqueous film that provides the same fast control and extinguishment as a top quality synthetic AFFF.

  • Film-forming for fast flame knockdown and extinguishment.
  • Stable and long-lasting foam blanket for excellent burn back resistance and post-fire security.
  • Detergent-free for high resistance to fuel pick-up.
  • Foam blanket re-seals when ruptured by personnel or equipment.
  • Reduced stocks, low cost storage, long shelf-life, and low usage levels combine to provide maximum cost effectiveness.


Petroseal 3% is readily biodegradable and virtually nontoxic to aquatic organisms. It is based on a natural protein foaming agent and contains no harmful synthetic detergent or glycol ether. Petroseal 3% can be successfully treated in biological waste water treatment systems.
