Which concentrate combines fluoroprotein with aqueous film forming capabilities?

• A. Film Forming Fluoroprotein Foam (FFFP) concentrate
• B. Protein concentrate
• C. Aqueous film forming concentrate
• D. High expansion concentrate

Answer: (A)

Film Forming Fluoroprotein Foam concentrates combine a protein base with fluorinated surfactants, giving both high surface stability and the ability to form a protective film on the fuel surface. The protein component provides strong coverage and burn-back resistance, while the fluorinated agents reduce surface tension and create an immediate, continuous film that spreads rapidly over hydrocarbons. This combination is what gives a concentrate its film-forming capability, making it the option that specifically blends fluoroprotein with film formation.
