PROCESSING AIDS FOR USE IN MANUFACTURING EXTRUDED POLYSTYRENE FOAMS USING LOW GLOBAL WARMING POTENTIAL BLOWING AGENTS

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 polymer...

Beschreibung
Zusammenfassung:	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 include 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 8.3MPa). Il est décrit un mélange polymère pouvant mousser qui comprend une composition polymère et au moins un gonflant. Le gonflant peut comprendre tous gonflants connus pour ne pas appauvrir l'ozone ou augmenter la prévalence du réchauffement de la planète, tels que CO2, HFO, HFC et des mélanges de ceux-ci. Le mélange polymère pouvant mousser peut en outre comprendre au moins un auxiliaire de traitement comprenant une matière de changement de phase organique. Le mélange pouvant former une mousse de la présente est capable de traiter à une plage de pression de 56 à 84 kg/cm2 (de 800 à 1 200 lb/po2) [de 5,5 à 8,3 mégapascals].
