Which new technology results in a foam with small, highly compacted bubbles that has excellent surface-adherence properties?

Explanation:
Compressed air foam systems create foam by combining foam concentrate with pressurized air, producing a multitude of tiny, tightly packed bubbles. That dense bubble structure forms a thick, cohesive blanket that clings to surfaces, blankets the fuel, and resists wind drift—providing strong cooling and knockdown. Traditional foams don’t generate the same small, compact bubbles or the same level of surface adherence, so they don’t lay down as durable a protective layer as CAFS.
