Foam formation meaning
WebFoam stability is defined as the time that foam will maintain its initial properties as generated. Foam stability is required during generation, transportation, and application to the fabric and has to be lost thereafter. Foams that are too stable are difficult to collapse; hence penetration into the fabric is poor.
