OLAS 33 is a synthetic film-forming foam, made from fluorine-containing surfactants and hydrocarbon-based surfactants, high molecular weight polymers, and various solvents.
OLAS 33 requires relatively low energy to form foam, and the resulting foam solution is capable of forming a film on most hydrocarbon material surfaces.
It also forms a polar, water-soluble material surface, such as alcohol-based solvents, acetone, etc.
These films separate the fuel from oxygen and prevent fuel evaporation. The water in the foam solution also acts as a coolant.
Suitable for use with saltwater, freshwater, and hard water at a mixing ratio of 3% or 3%.
OLAS 33 should be used at a mixing ratio of 3% for Class B fires (hydrocarbon fuels) or 3% for polar solvent fires.
The excellent wetting properties of OLAS 33 also make it suitable for fire types
OLAS 33 can be used with low-expansion foam sprayers (nozzles) and sprayers (mist nozzles,standard nozzles).
