Fomtec Enviro USP is a fluorine-free foam consisting of selected hydrocarbon surfactants, solvents and stabilizers to give optimal fire performance. Fomtec Enviro USP is especially designed to be an effective fluorine-free alternative for sprinkler systems, type II and III discharge devices. Fomtec Enviro USP should be used at 2% with fresh water for low, medium and high expansion discharge devices. For sprinkler systems it should be used in 3% proportioning. For use on class A type fires induction ratio of 0.5-1% is recommended depending on application and discharge device.


  • New Generation Fluorine Free Foam
  • All In One Foam: Made for any type of foam discharge devise and sprinkler system on the market
  • For Class A & B Hydrocarbon Fires & Fully Biodegradable
  • Approved: As Low, Medium & High Expansion Foam
  • Induction: 0,5-1% Class A, 2% EN1568, 3% Sprinkler Fires
  • Superior Fire Performance: Rate 1A, EN 1568 Part 3


Fomtec Enviro USP is intended for use on class B hydrocarbon fuel fires such as oil, diesel and aviation fuels as well as class A fires such as wood, paper, textiles etc. Fomtec Enviro USP is especially suited whenever a fluorine-free alternative with high fire performance is requested. It is compatible with all dry chemical powders and can be used in powder/foam twin agent systems.

Fire Performance & Foaming

The fire performance of this product has been measured and documented according to “International Approvals” stated in this document. The design parameters depend on type of system and application. The use of the product should follow design guidelines. The foaming properties are depending on equipment used and other variables such as water and ambient temperatures. Average expansion 7,5:1, average ¼ drainage time 25:00 minutes using UNI 86 test nozzle.


Fomtec Enviro USP can easily be proportioned at the correct dilution using conventional equipment such as:

The equipment should be designed to the foam type.

  • Inline inductors
  • Inline Balanced Pressure, proportioning systems (ILBP)
  • Bladder tanks and ratio controllers
  • Around the pump proportioning systems
  • Water motor or turbine driven foam proportioners
  • Self inducting branch pipes and nozzles

Environmental impact

Fomtec Enviro USP is formulated using specially selected raw materials, selected for their fire performance and their environmental profile. Fomtec Enviro USP is fully biodegradable and contain no fluorinated compounds.
The handling of spill of concentrate or foam solutions shall however be made according to local regulations. Normally sewage systems will have no problem with a 3% foam solution based on Fomtec Enviro USP, but local sewage operators should be consulted in this respect.

Storage / Shelf life

Stored in original unbroken packaging the product will have a long shelf life. Shelf life of 10-20 years will be found in temperate climates. As with all foams, shelf life will be dependent on storage temperatures and conditions.

Synthetic foam concentrates should only be stored in stainless steel or plastic containers. Since electrochemical corrosion can occur at joints between different metals when they are in contact with foam concentrate, only one
type of metal should be used for pipelines, fittings, pumps, and tanks employed in the storage of foam concentrates. We recommend following our guidelines for storage and handling ensuring favourable storage conditions.


We supply this product in 25 litre and 5 US gallon cans, 200 litre and 55 US gallon drums, 1000 litre and 275 US gallon IBC containers and in bulk on special request.
