Abstract

L'invention concerne des procédés et des compositions destinés à former des mousses viscoélastiques souples à alvéoles ouvertes qui utilisent une composition thermodurcissable comprenant un ou plusieurs constituants capables de former une matrice thermodurcie et un agent d'expansion comprenant au moins un agent d'expansion chimique, tel que l'eau, et au moins un agent d'expansion physique choisi dans le groupe constitué du trans-l-chloro -3,3,3-trifluoropropène (hfco-1233zd(e) ), du 1,1,1,3,3-pentafluoropropane (hfc-245 fa), du 1,1,1,3,3-pentafluorobutane (365mfc), des mélanges constitués essentiellement d'au moins environ 80% de hfc-365 mfc et de 1,1,1,2,3,3,3-heptafluoropropane (227ea), et des combinaisons de deux quelconques ou plus de ces derniers.Methods and compositions for forming flexible open-cell viscoelastic foams using a thermosetting composition comprising one or more components capable of forming a thermoset matrix and an expanding agent comprising at least one chemical expansion agent , such as water, and at least one physical blowing agent selected from the group consisting of trans-1-chloro-3,3,3-trifluoropropene (hfco-1233zd (e)), 1,1,1 , 3,3-pentafluoropropane (hfc-245 fa), 1,1,1,3,3-pentafluorobutane (365mfc), mixtures consisting essentially of at least about 80% hfc-365 mfc and 1.1 , 1,2,3,3,3-heptafluoropropane (227ea), and combinations of any two or more thereof.
