Title (EN) POLYOLEFIN FOAMS MADE WITH ISOPENTANE-BASED BLOWING AGENTS
(FR) MOUSSES POLYOLEFINIQUES FABRIQUEES AVEC DES AGENTS DE GONFLEMENT A BASE D'ISOPENTANE
Abstract: front page image
(EN)A blowing agent blend for making polyolefin foams comprising isopentane and at least one co-blowing agent. The co-blowing agent is either a physical co-blowing agent having a boiling point less than 28 °C, or a chemical co-blowing agent, or combinations thereof. The blowing agent blend comprises less than about 99 mol % isopentane.
(FR)L'invention concerne un mélange d'agents de gonflement servant à fabriquer des mousses polyoléfiniques comprenant de l'isopentane et au moins un agent de co-gonflement. Cet agent de co-gonflement est soit un agent de co-gonflement physique dont le point d'ébullition est inférieur à 28 °C, soit un agent de co-gonflement chimique, soit des combinaisons de ces derniers.
