Abstract

Procedure for the manufacture of phenolic foams from a resole obtained by reaction of phenol and formaldehyde in a basic medium, characterized in that the resole is concentrated until obtaining a product that has a dry extract content, measured according to the method described, at less than 85% and a viscosity greater than 1000 poises, the product thus obtained is mixed at a temperature of approximately 60ºC with a blowing agent and with a slightly active acid catalyst at the indicated temperature and the mixture is expanded and hardened by heating at a temperature between approximately 80-100ºC.
