Which foam type is fluorinated?

Which foam type is fluorinated?

• A. AFFF
• B. Fluoroprotein Foam
• C. Protein Foam
• D. High-Expansion Foam

Answer: (B)

Fluorination in foam means the formulation uses fluorinated surfactants that lower surface tension and help create a stable film on hydrocarbon fuels. Fluoroprotein foam is a blend of a protein base with fluorinated surfactants, combining the robustness of protein foam with the low-surface-tension and film-forming properties of fluorination. That makes fluoroprotein foam the fluorinated option in this list. Pure protein foam relies on protein-derived stabilizers without fluorinated additives, and high-expansion foam is defined by its large air content rather than fluorination. (AFFF also uses fluorinated surfactants in many versions, but this item identifies fluoroprotein as the fluorinated choice.)
