foam stability

Foam stability refers to how well a foam maintains its structure over time without collapsing or breaking down. In practical terms, it’s how long a foam can hold its bubbles and continue being effective. Factors like the ingredients in the foam, the size of the bubbles, and environmental conditions influence stability. For example, in firefighting foam, stability ensures it stays effective long enough to suppress a fire. Generally, high stability means the foam remains intact longer, providing better performance, while low stability leads to quick breakdown and reduced effectiveness.
