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.

  • Highly fluid foam for rapid fire knockdown and extinguishment.
  • Exceptional burnback resistance and post-fire security.
  • 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.
  • Used with air aspirating discharge devices.
  • Suitable for use with fresh or sea water.

Performance Approvals

  • FP70C6 is independently tested and certified to EN1568:2008 part 3.
  • Passed LastFire with excellent results.
  • Audited and approved to Underwriters Laboratories UL162 (7th Edition).


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. With medium expansion equipment it can also be used at 3%, but for optimal results a 6% induction rate is recommended.

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.

FP70C6 is suitable for use in combination with:

  • Soft or hard, fresh, brackish or sea water.
  • Dry powder extinguishing agents either separately or as twin agent systems.
  • Expanded protein-based or synthetic foams for application to a fire in sequence or simultaneously.


FP70C6 foam concentrate is exceptionally stable in long-term storage. A shelf-life of at least ten years can be expected if it is stored properly.


FP70C6 is produced to rigorous quality control standards to ensure consistent fire performance and excellent product reliability.
