FP70 C6

3% FluoroProtein Foam Concentrate (FP)

FP70C6 is a superior quality FluoroProtein (FP) 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 provides a tough cohesive foam blanket with high resistance to heat that quickly smothers, cools, and seals the risk. Fluorochemical surface active agents combined with the protein base increase the fluidity and fuel repellency of the foam.

  • Stable long-lasting foam blanket for unsurpassed burnback resistance and post-fire security.
  • Highly fluid foam for rapid fire knockdown and extinguishment.
  • Detergent-free for high resistance to fuel pick-up.
  • Excellent sealing action on hot metal surfaces.
  • Foam blanket re-seals when ruptured by personnel or equipment.

Performance Approvals

  • FP70C6 has numerous approvals and UL Listings against Underwriters Laboratories Standard UL 162 (7th Edition).
  • Independently Tested and Certified to EN1568:2008 Part 3.

Environmental Impact  

FP70C6 is based on a natural protein foaming agent and contains no harmful synthetic detergent or glycol ether. 


FP70C6 is the ideal fire fighting foam to use in situations where hydrocarbon fuels such as crude oil, gasoline, and fuel oils are stored, processed or transported. It is used extensively by major world oil and petrochemical companies for tank fire protection. 

FP70C6 provides a vapour-suppressing foam blanket on unignited hydrocarbon spills.


FP70C6 is intended for use as a 3% solution in water (3 parts concentrate to 97 parts water) at low expansion, and as a 6% solution in water at medium expansion.

It is readily proportioned using conventional foam proportioning equipment such as portable and fixed foam proportioners.

FP70C6 should be used with air aspirating discharge devices such as low expansion branchpipes, monitors, top pourer sets. 

As with any foam, FP70C6 is best applied gently on to the burning liquid surface. However, its exceptional resistance to fuel contamination enables it to withstand vigorous mixing with fuel. This makes it ideal for forceful application on to storage tank fires from ground-based mobile monitors or through base (sub-surface) injection systems.
