Abstract
Stable, liquid phenolic froths have been produced by whipping air into a mixture of phenolic resole, catalyst and surfactant. These liquid froths can be moulded into desired shapes and cured to produce open porous phenolic foams. This method, which we call froth templating, has been scaled to produce macroporous phenolic foam panels with a size of 400 mm
