Abstract

L'invention porte sur la production de mousses de résol à basse densité à partir de résines de résol. Lesdites mousses, d'une densité de 2,0 livres par pied cubique (32,037 kg/m<3>) ou moins, sont obtenues à l'aide d'un agent porogène à bas point d'ébullition tel que le HCFC ou le perfluoroalkane.
