With the continuous advancement of science and technology, all industries have achieved rapid development. Aqueous film-forming foam fire extinguishing agents enjoy promising prospects, driving growing market demand and a rising number of manufacturers. As a producer, we hereby introduce relevant basic knowledge for your reference.

People often have doubts before using this product. Mastering its properties helps achieve proper application. This agent features sound solvent resistance and can be widely used to put out various fires in diverse environments.

When applied to burning oil or polar solvents, the foam flows and spreads rapidly over liquid surfaces, covering areas beyond direct spraying range. It forms a tight sealing water film to separate combustibles from air. Based on hydrocarbon and fluorocarbon surfactants, it can form protective water films and is suitable for fighting fires caused by water-soluble liquid fuels.

The spreading coefficient evaluates the spreading capacity of one liquid on another. Its fire extinguishing performance is assessed with reference to standard fuels, application methods, reaction time and fire resistance grades.

It is applicable to submerged discharge fire fighting. It works effectively on petroleum, petroleum products and other water-insoluble substances, and also delivers excellent fire suppression effect against water-soluble flammable liquids including alcohols, esters, ethers, aldehydes, ketones and amines.

Anti-solvent ingredients inside prevent water absorption by water-soluble solvents and maintain foam integrity. Fire is put out through the combined effect of foam coverage and protective film, greatly boosting on-site fire fighting efficiency.

Liquid discharge operations shall adopt protein, fluoroprotein, film-forming fluoroprotein or aqueous film-forming foam solutions. The fire resistance grade of selected agents shall not be lower than Grade C specified in national standard GB 15308 Foam Fire Extinguishing Agents.

Domestically developed products feature low surface tension, fast fire suppression speed, high efficiency and favorable fluidity.

The above content presents the prominent characteristics of aqueous film-forming foam fire extinguishing agents. More relevant information will be updated continuously.
