Title
(EN) ENDOTHERMIC BLOWING AGENTS COMPOSITIONS AND APPLICATIONS
(FR) COMPOSITIONS ET APPLICATIONS D'AGENTS GONFLANTS ENDOTHERMIQUES
Abstract
(EN)
A stabilized powdered endothermic blowing agent which is a mixture of polycarboxylic acid and an inorganic carbonate, the polycarboxylic acid and the inorganic carbonate each having been surface treated with a component which prevents water from being absorbed thereby. The blowing agent is incorporated into a composition for producing foamed products. Additives may be added to the composition which function in conjunction with the blowing agent to cause surface migration of the additives and/or improve weld line strength of the foamed products.
(FR)
Un agent moussant endothermique stabilisé en poudre est un mélange d'acide polycarboxylique et d'un carbonate inorganique, l'acide polycarboxylique et le carbonate inorganique étant traités tous les deux en surface avec un composant qui les empêche d'absorber l'eau. L'agent moussant est incorporé à une composition de production de produits alvéolaires. On peut ajouter à la composition des additifs qui coopèrent avec l'agent moussant de façon à provoquer une migration superficielle des additifs et/ou améliorer la résistance des cordons des lignes de soudure des produits alvéolaires.
