Abstract

Method for producing an open-cell, acid-resistant phenolic foam, comprising the operations of mixing together 100 parts; by weight of a resole resin, from 0.5 to 3.0 parts by weight of a wetting agent, from 1 to 20 parts by weight of a blowing agent, and a suitable acid catalyst to expand and polymerize the resin leaving the foam forms a self-sustaining mass that has a protective skin on the outer surface, remove the skin from the outer surface of the dough, and heat-cure the dough maintaining the inside of the dough from 149ºC to 183º c.
