What is Ansulite?

ANSULITE®​ Alcohol-Resistant Aqueous Film-Forming Foam (AR-AFFF) Concentrates produce a foam that is effective on hydrocarbon fuels as well as fuels such as methanol, ethanol and acetone which have appreciable water solubility or miscibility.

What type of foam is used for polar solvents?

Alcohol-Resistant
Alcohol-Resistant (AR) foam is a combination of synthetic stabilizers, foaming agents, fluorochemicals, and synthetic polymers designed for use on polar solvents. The chemical makeup of these foams prevents the polar solvents from destroying them.

What is AR AFFF foam used for?

Alcohol Resistant Aqueous Film Forming foams, AR-AFFF, are especially effective for extinguishing and securing flammable hydrocarbon and polar solvent fires. High risk facilities such as refineries, pharmaceutical plants, process areas often require AR AFFF foams.

Is AR AFFF Class B foam?

CHEMGUARD Alcohol Resistant Aqueous Film-Forming Foam Concentrates (AR-AFFF) combine fluoro- and hydrocarbon-surfactant technologies to provide superior fire and vapor suppression for Class B, polar solvent and hydrocarbon fuel fires.

What is a polar solvent fire?

Polar Solvent: In fire fighting, any flammable liquid which destroys regular foams. Polar solvents aggressively attack the bubble by mixing with the water in the bubble structure. Polar solvents require special foam agents and mix ratios. Examples: esters, ethers, alcohols, aldehydes and keytones.

What is class A foam?

Class A foams are used to extinguish fires caused by wood, paper, and brush. Class A foams generally do not contain per- and polyfluoroalkyl substances (also known as “PFAS”).

What is class B foam made of?

Class B foams can be protein foams or synthetic foams. Protein foams contain natural proteins and are generally biodegradable; synthetic foams are made of synthetic foaming agents.

What is the difference between AR AFFF and AFFF?

OFAFFF AND AR-AFFF AFFF and AR-AFFF consist of essentially the same ingredients. These typically include fluorosurfactants, hydrocarbon surfactants, solvents, inorganic salts, corrosion inhibitors, water; and in the case of AR- AFFF, a polymer which is typically a polysaccharide.

How long is AFFF foam good for?

between 20-25 years
If kept in the original unopened and airtight Chemguard supplied container and stored within the temperature range of 35ºF – 120ºF (2ºC – 49ºC) a shelf life of between 20-25 years can be expected.

What is the difference between Class A and Class B foam?

There are many different types of foam for firefighting: Class A foam is used for combustibles, structural fires and wildfires; Class B foam is used for ignitable liquids, like gasoline and diesel; and polar solvent foams help extinguish alcohol-based liquids and alcohol-type fuels.

What class of foam is AR AFFF?

Class B Foam
Class B Foam (also called AFFF): Used to extinguish Class B materials, which include gasoline, oil, and jet fuel.
