Multi purpose foam Fomtec Enviro 3×3 Plus

Enviro 3×3 Plus

Fomtec Enviro 3×3 Plus is a multi-purpose alcohol resistant fire fighting foam totally free from fluorinated surfactants and polymers.
The foaming characteristics of Fomtec Enviro 3×3 Plus allows the foam to fast spread across the burning liquid and get control of the fire. Fomtec Enviro 3×3 Plus has been designed to work effectively on both hydrocarbon and polar fires.
When applied on polar solvents a polymeric membrane is formed and makes it possible for the foam blanket to extinguish effectively. It also works on severe foam destroying liquids such as MTBE.
Fomtec Enviro 3×3 Plus should be used at 3% proportioned solution both on hydrocarbon liquids and polar solvents. When used with sea water the fire performance is reduced.


Fomtec Enviro 3×3 Plus is intended for use on class B hydrocarbon fuels as well as polar solvents like isopropyl alcohol, methanol, ethanol, acetone etc. Fomtec Enviro 3×3 Plus can be used as low and medium expansion foam.

Fire Performance & Foaming

The fire performance of this product has been measured and documented according to “International Approvals” stated in this document. The foaming properties are depending on equipment used and other variables such as water and ambient temperatures. Average expansion 7:1, average ¼ drainage time 18:30 minutes using UNI 86 test nozzle.


Fomtec Enviro 3×3 Plus can easily be proportioned at the correct dilution using conventional equipment such as:

  • Inline inductors
  • Balanced pressure, variable flow proportioning systems
  • Bladder tanks
  • Around the pump proportioning systems
  • Water turbine driven foam proportioners
  • Self inducting branch pipes and nozzles

The equipment should be designed to the foam type.

Environmental impact

Fomtec Enviro 3×3 Plus is formulated using raw materials specially selected for their fire performance and their environmental profile. Fomtec Enviro 3×3 Plus is biodegradable. The handling of spills of concentrate or foam solutions should however be undertaken according to local regulations. Normally sewage systems can dispose foam solution based on this type of foam concentrate, but local sewage operators should be consulted in this respect.

Full details will be found in the Material Safety Datasheet (MSDS).

Storage / Shelf life

Stored in original unbroken packaging the product will have a long shelf life. Shelf life in excess of 10 years will be found in temperate climates. As with all foams, shelf life will be dependent on storage temperatures and conditions. If the product is frozen during storage or transport, thawing will render the product completely usable.
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.
