Fomtec Enviro USP


Fomtec Enviro USP is a novel fluorine free firefighting foam totally free from fluorinated surfactants and polymers (PFAS).
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 can 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. Fomtec Enviro USP can be used with sea water when used as a 6% mixture. For polar solvents it recommended to use between 6% to 9% depending on fuel type and water quality.

More Information


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 (PFAS) with high fire performance is required. Approved for use in sprinkler systems as per UL listing. Suitable for mobile firefighting by use of aspirating foam discharge devices such as foam branchpipes and monitors, where appli- cation rates and technique can be adjusted to the specifics
of each incident. Or in systems designed for use with the product based on recommended minimum applications rates, application duration and discharge devices.

Fire performance & Foaming
TThe 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 7:1, average ¼ drainage time 25:00 minutes using UNI 86 test nozzle.

Fomtec Enviro USP can be used together with foam compatible powders and other expanded foams. It is only intended for use with fresh water.
Fomtec Enviro USP concentrate should not be mixed with other foam concentrates.
For material compatibility please refer to Fomtec Technical Advices FTA 20 addressing the topic.
Tested to Boeing Specification Support Standard BSS7432 with conformity on all test parameters.

Fomtec Enviro USP is formulated using raw materials specially selected for their fire performance and their environmental profile. The product is totally free from fluorinated surfactants and polymers and other organohalogens, and therefore it does not contain any PFAS. Fomtec Enviro USP is 100% biodegrad-able. 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.
Full details will be found in the Material Safety Datasheet
(MSDS). For more detailed information please consult Fomtec Technical Advices FTA 40.

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 depen-dent on storage temperatures and conditions.
For storage recommendations and material compatibility please refer to our Fomtec Technical Advices FTA 10 addressing the topic.

The foam concentrate should be tested annually. The testing should be made by a suitable laboratory for analysis of foam concentrates and should measure: pH, specific gravity, expansion, drainage time. Storage containers should be inspected and reevaluated for the suitability of the storage location in regard to temperature fluctuations (temperature should be as stable as possible). Exposure to direct sunlight should be avoided.



Dafo Fomtec AB is a privately owned company with head office in Stockholm, Sweden and manufacturing in Helsingborg in the south of Sweden.

Fomtec’s philosophy is that any foam system must consist of components that have been tested and approved for its intended use as a part of a system proven to work in harmony.

This is critically important when using fluorine free foams because the effectiveness of these foams is much more dependent on the quality (expansion ratio, drainage time and bubble structure) of the foam generated by the system, than fluorinated foams are.

Fomtec is committed to meet and exceed the standards we set behind our company’s core values of: Performance • Trust • Sustainability
