What is the difference between AFFF and AR-AFFF?
What is the difference between AFFF and AR-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.
Does AFFF expire?
When stored in the packaging supplied (polyethylene drums or pails) or in equipment recommended by the manufacturer as part of the foam system and within the temperature limits specified, the shelf life of ANSULITE ARC 3% or 6% AR-AFFF Concentrate is about 20-25 years.
What is 3% AFFF used for?

What is AFFF fire extinguisher?
AFFF Foam Fire Extinguishers provide a fast, powerful means of tackling flammable liquids. The foam forms a seal over the surface to prevent re-ignition. Ideal for multi-risk usage. Most commonly used in offices, garage forecourts, factories and shops.
What kind of foam is fomtec AFFF 1% a?
AFFF 1% A. Fomtec AFFF 1% A is an aqueous film forming foam concentrate (AFFF) consisting of fluorocarbon and hydrocarbon surfactants blended with various solvents, preservatives and stabilisers.
What kind of fire extinguisher uses AFFF foam?
While foams are primarily desired protection for class “B” flammable liquid hazards, the wetting and cooling characteristics of an AFFF foam solution, also make them effective on class “A” common combustible types of fires. Some typical applications include the following:
When to use chemguard AR-AFFF foam concentrates?
The concentrates also have excellent wetting properties that can effectively combat Class A fires and may be used in conjunction with dry chemical agents to provide even greater fire suppression performance. CHEMGUARD AR-AFFF foam solutions utilize three suppression mechanisms intended for rapid fire knockdown and superior burnback resistance:
What kind of foam is used for firefighting?
AFFF 1% A. Fomtec AFFF 1% A is an aqueous film forming foam concentrate (AFFF) consisting of fluorocarbon and hydrocarbon surfactants blended with various solvents, preservatives and stabilisers. The foam forms an aqueous film that rapidly cuts off the oxygen supply and knocks down the fire.
