Chemguard 1% AFFF is a specially formulated, synthetic, aqueous film forming foam concentrate. A vapor suppressing aqueous film is formed by the foam solution draining from the expanded foam blanket. It is intended for use at a proportioning rate of 1% (1 part AFFF concentrate to 99 parts water) on Class B hydrocarbon type fuels such as gasoline, kerosene, diesel, etc. Chemguard 1% AFFF is not intended for use on fuels, which are polar solvent/water miscible such as alcohols, ketones, esters, etc.
FEATURES
U.L. Listed, Foam Liquid Concentrates
U.L. recommended application rate on hydrocarbon type fuels is .10/gpm ft².
FM Approved
Suitable for use with either fresh or salt water
Excellent wetting characteristics when used in combating Class A fuel type fires
Suitable for use with both air-aspirating foam and standard water fog nozzles
Suitable for use with deluge or closed head foam water sprinkler systems
If inadvertently frozen, thawing will render product completely serviceable again
Suitable for use with carbon steel, fiberglass, polyethylene or stainless steel. Chemguard 1% AFFF is not compatible with galvanized pipe or fittings in an undiluted form.
Suitable for use with dry chemical extinguishing agents.

FOAM PROPERTIES
Aspirating type discharge devices typically generate expansion ratios between 6-10 to 1 when 1% AFFF is mixed with water at the correct ratio. Non-aspirating type devices will typically generate expansion ratios of between 2-4 to 1. Expansion ratios are dictated by the type of discharge device, flow rate and discharge pressure.
