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.
摘要:
A foamable polymeric mixture is provided that includes a polymer composition and at least one blowing agent. The blowing agent may comprise any blowing agents known not to deplete the ozone or increase the prevalence of global warming, such as CO2, HFO, HFC and mixtures thereof. The foamable polymeric mixture may further includes at least one processing aid comprising an organic phase changing material. The inventive foamable mixture is capable of processing at a pressure range of 800 to 1200 psi (5.5 to 8.3 MPa).
