Aqueous Film Forming Foam (AFFF) refers to a kind of foam extinguishing agent that can quickly spread out on the surface of liquid fuel and form a dense foam layer and water film layer in the process of fire extinguishing.

Alcohol resistant aqueous film-forming foam extinguishing agent(AR-AFFF) refers to the addition of some additives (such as metal soap, bioactive polysaccharide) in AFFF to change its chemical polarity so that the two will not be mutually soluble, so that the polar solution can also be a certain stable water film such as methanol, ethanol, etc

Fluorocarbon surfactants are its core components, mainly used in AFFF C6, C8 carbon chain fluorocarbon surfactants, the longer the carbon chain, the more stable the product, the more lasting toxicity to the environment. So C8 fluorocarbon surfactants have been gradually banned, and C6 fluorocarbon surfactants need to be combined with other surfactants to achieve the effect of C8 formulation, alkyl polyglycosides are one of the best options.
