Foam concentrates

FOAM CONCENTRATES

How is foam actually generated? Just think of a child blowing bubbles. We add some shampoo (i. e. foam concentrate) to the water in a bowl and mix both (making a foam solution). We dip into it a loop made of a material that can be moistened (the foam-generating device) and blow air into the middle of the round film of foam solution on the loop after it has been lifted out of the water (foam-generation), and a series of rainbow-coloured bubbles float upwards, a real miracle!

Foam concentrates

Basically, the foam-generating material or the foam concentrate serves a similar purpose in fire protection, as the shampoo mentioned above. Let us look at how it works then – after having explained some basic notions.

The foam concentrate is a water-soluble material that reduces the surface tension of water (it makes the water softer, thus the water becomes foamier, see washing in rainwater). In addition to generating bubbles, the fire-extinguishing capability of the foam material depends on its ability to generate a film (AFFF, AFFF/AR). At present, the long-term impact of foam concentrates on the environment is being examined and materials that might pose a threat to the environment are banned internationally.

Foam solution: the solution of water and foam concentrate. It is used in different concentrations (as a rule, 0.1 to 6% of foam concentrate). If air or gas is added to it, it produces long-lasting foam; with certain types, 1 or 2 fire-preventive films are generated on the surface of the liquid to be extinguished (AFFF).

Synthetic foam material: foam-generating material of good foaming capability, also suitable for generating light foam.

AFFF foam: in addition to its foaming capability, AFFF foam can generate a film and is also suitable for extinguishing liquids that can destroy foam and the film-generating feature multiplies, synergically, the foam's extinguishing capability, thereby resulting in a more efficient extinguishing process.

Illustration of foam materials

Double film-generating foam: The AFFF/AR double film-generating foams can also be deployed efficiently against liquids that destroy foam, such as alcohol or acetone. This type of foam is also called alcohol-resistant foam. The point of the double film-layer is that the foam solution

  • also composes a surface film with the liquid to be extinguished (we can imagine this as if we dripped thin spindle oil on a water-surface in a washing bowl and that drip would cover the whole surface with an oil-film) the material of which consists of the inflammable liquid and of the foam solution, and
  • it also composes another film-layer with the foam solution of the extinguishing foam, the film material of which is constituted by the mixture of the foam solution and of the foam-generating material (continuing the above concept, we can imagine this as if we let a water –film layer spread on the surface of the spindle oil film and the extinguishing foam itself would be positioned above this.)

Sprinkler-1 Ltd. supplies the synthetic foam materials in a concentration of 0.5 to 3%, subject to function and to the customer's demands.

We offer the AFFF film-generating foam materials and the AFFF/AR alcohol-resistant film-generating materials in a foam solution concentration of 3 to 6%.

We look forward to your inquiries!
