MB High Expansion Foam

MB 5
Fomtec MB 5 is a multi purpose foam which can be used at low, medium and high expansions for the extinguishment of class B hydrocarbon fires such as small fuel spills (low & medium expansion), bench protection (medium expansion), and it can also be used for the control and extinction of cryogenic flammable liquid fires or vapour release from toxic spillage. At medium and high expansion, Fomtec MB 5 can be used for total flooding of fires involving class A and class B materials. Medium expansion type is particularly suitable for small areas such as cellars and basements of buildings and high expansion type for large areas such as ship cargo or engine rooms. It is especially suitable for dealing with fires in inaccessible locations and where damage must be kept to a minimum.

Description
Fomtec MB 5 is a blend of high activity, synthetic, fatty alcohol sulphates, solvents and stabilisers.

Fomtec MB 5 mixed with water and converted into finished foam via low, medium or high expansion foam making equipment combats fires by engulfing the area, restricting the supply of oxygen, cooling of the liquid surface, and the suppression of flammable gases evaporating from the hot liquid surface. Used as high expansion in complete filling of enclosed rooms the foam creates an inert atmosphere.

Fomtec MB 5 should be used between 2% and 6% concentration in fresh or sea water if medium or high expansion foams are required depending on equipment used.

Foaming Properties
The expansion will vary depending on the characteristics of the equipment used.

Proportioning
Fomtec MB 5 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
High expansion foam generators.

Storage/Shelf Life
Stored in original unbroken packaging the product will have a long shelf life. The recommended storage temperature range of Fomtec
MB 5 is from -2°C to 49°C. Freezing and thawing will have no impact on the performance.
Synthetic foam concentrates should only be stored in stainless steel or plastic containers. Since electromagnetic 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.
Packaging
