Beschreibung
Zusammenfassung:	A foamable polymeric mixture is provided that includes a polymer composition, at least one blowing agent, and at least one non-VOC processing aid comprising one or more of an adipate ester; benzoate; fatty acids and their derivatives, propylene carbonate; ethylene oxide/propylene oxide block copolymer; styrene-methyl methacrylate copolymer; and a dispersion of organic salt of a fatty acid in copolymer. The blowing agent comprising at least one of carbon dioxide, hydrofluoroolefins, hydrochlorofluoroolefins and hydrofluorocarbons, and mixtures thereof. L'invention concerne un mélange polymère expansible qui comprend une composition polymère, au moins un agent gonflant, et au moins un auxiliaire de traitement sans COV comprenant au moins un des éléments suivants: l'ester d'adipate; le benzoate; des acides gras et leurs dérivés, du carbonate de propylène; un copolymère bloc d'oxyde d'éthylène/oxyde de propylène; un copolymère de styrène-méthacrylate de méthyle; et une dispersion de sel organique d'un acide gras dans le copolymère. L'agent gonflant comprend du dioxyde de carbone et/ou des hydrofluorooléfines et/ou des hydrochlorofluorooléfines et/ou des hydrofluorocarbones, et des mélanges de ceux-ci.
