Title (EN) PHENOLIC RESIN FOAM
(FR) RESINE PHENOLIQUE EXPANSEE
Abstract: front page image
(EN)A phenolic resin foam which is obtained by using a hydrocarbon as a foaming agent having no fear of ozonosphere depletion and a low coefficient of global warming, has excellent heat-insulating performance, and is excellent in mechanical strengths such as compression strength and reduced in brittleness. This foam has a closed-cell content of 70 % or higher, an average cell diameter of 10 to 400 $g(m)m, and a density of 10 to 70 kg/m?3¿ and gives through pyrolytic gas chromatography a pyrolysis pattern in which the ratio C of the area A for all trimethylphenols as pyrolysis products to the area B for phenol as another pyrolysis product (C=A/B) is in the range defined by equation (1): 0.05 $m(F) C $m(F) 4.0.
(FR)L'invention porte sur une résine phénolique expansée utilisant comme agent moussant un hydrocarbure ne contribuant pas à l'appauvrissement en ozone, et faiblement au réchauffement du globe, excellent isolant thermique et d'une excellente résistance mécanique notamment à la compression et peu fragile. Ladite résine comporte 70 % ou plus de cellules fermées d'un diamètre moyen de 10 à 400 $g(m)m, sa densité est comprise entre 10 et 70 kg/m?3¿ et elle produit par chromatographie gazeuse pyrolytique un diagramme de pyrolyse dans lequel le rapport C de l'aire A de tous les triméthylphénols produits de la pyrolyse à l'aire B des phénols autres produits de la pyrolyse (C=A/B) est défini par l'inégalité 0,05 $m(F) C $m(F) 4,0.
