Abrégé
(EN)
Improved microcellular and ultramicrocellular materials containing hydrofluorocarbon (HFC) inflatants are disclosed. The inflatants are environmentally more favorable than fully halogenated chlorofluorocarbons (CFCs).
(FR)
On décrit des matériaux microcellulaires et ultra-microcellulaires améliorés contenant des agents gonflants à base d'hydrofluorocarbure (HFC). Les agents gonflants sont plus bénéfiques pour l'environnement que des chlorofluorocarbones entièrement halogénés (CFC).
