◆ 1：The Aqueous Film Forming Foam (AFFF) concentrate is composed of fluorocarbon surfactants, fluorine-free surfactants (carbon-chlorine surfactants or silicone surfactants), additives (foam stabilizers, antifreeze agents, cosolvents, and thickener, etc.) that can improve foam performance, and water. It is categorized into 3% AFFF (3:97) and 6% AFFF (6:94) based on the mixing ratio with water.
◆ 2：The alcohol-resistant aqueous film-forming foam (AR-AFFF) concentrate is a multi-functional environmentally friendly fire foam that is composed of hydrocarbon surfactants, fluorocarbon surfactants, anti-drying agents, additives, polar film-forming agents, stabilizers, antifreeze agents, preservatives, foaming agents, etc. It is categorized into 3% AFFF/AR (3:97) and 6% AFFF/AR (6:94) based on the mixing ratio with water. The shelf life is eight years. The alcohol-resistant component only works for two years, after which it becomes an ordinary aqueous film-forming fire extinguishing agent.
