quickly extinguish fires caused by polar (water-soluble) flammable solvents such as alcohols, esters, ethers, aldehydes, ketones, and organic acidslow-expansion foam generating equipment to foam and extinguish fires with fresh water at a ratio of 6:94for extinguishing non-polar solvent fires is Class I A , and the fire-extinguishing level for extinguishing polar solvent fires is AR I- B .Product Description
6% (AFFF/AR, - 6 ℃) (also known as light water anti-solvent foam fire extinguishing agent) is a low-expansion foam fire extinguishing agent, which is composed of composite surfactants, co-solvents, polar film-forming agents, stabilizers, antifreeze agents, preservatives, etc. Formulated with water. In addition to the performance of general aqueous film-forming foam fire extinguishing agents in quickly extinguishing oil fires, it also has the ability to form a layer of condensation on the surface of polar flammable liquids due to the polar film-forming agent added to the formula. The adhesive film protects the fire-extinguishing foam from being destroyed, so it has the ability to quickly extinguish fires caused by polar (water-soluble) flammable solvents such as alcohols, esters, ethers, aldehydes, ketones, and organic acids. It is an efficient and multi-functional fire-extinguishing agent. It can use various low-expansion foam generating equipment to foam and extinguish fires with fresh water at a ratio of 6:94. The fire-extinguishing level of this product for extinguishing non-polar solvent fires is Class I A , and the fire-extinguishing level for extinguishing polar solvent fires is AR I- B .
Application
It can extinguish liquid fire effectively and quickly. It is not only widely used in oil fields, oil depots, refineries, ships, airports, chemical plants and units that store large amounts of oil products to quickly put out large-area oil fires, but is also suitable for putting out flammable alcohols, esters, ethers, organic acids, amines, ketones, etc. Polar solvent fires can also be quickly extinguished.

Product Advantages
Because it contains fluorocarbon surfactant, the foam solution (dilution with water) has extremely low surface tension. During the fire extinguishing process, it can form a protective film on the surface of hydrocarbon fuels that inhibits the evaporation of hydrocarbons. It relies on the dual functions of foam and protective film to extinguish fires. It can control fire fatly, extinguish fire rapidly and efficiency; It has good fluidity, strong self-sealing ability, and good re-ignition prevention. It is not only suitable for oil fires, but also has excellent extinguishing properties. Ability to fire with polar solvents such as esters, ketones, aldehydes, and ethers. Moreover, the product is easy to store. During storage and use, it has the advantages of no odor, no pollution, no corrosion of equipment, no residue, stable storage, and harmless to the body during normal use.
