Beschreibung
Zusammenfassung:	A composition and process to make polyisocyanurate or polyurethane foam using a catalyst composition comprising at least one bismuth carboxylate catalyst and one or more co-catalysts selected from the group of alkali metal carboxylates and quaternary ammonium carboxylate salts, such that the resultant foam has improved insulation properties. The polyisocyanurate or polyurethane foams produced by this catalyst composition and method are useful for laminated boardstock, construction panels, appliance insulation, and spray-applied insulation. Una composición y proceso para hacer espuma de poliisocianurato o poliuretano utilizando una composición de catalizador que comprende por lo menos un catalizador de carboxilato de bismuto y uno o más co-catalizadores seleccionados del grupo de carboxilatos de metal alcalino y sales de carboxilato de amonio cuaternario, tal que la espuma resultante tiene propiedades de aislamiento mejoradas. Las espumas de poliisocianurato o poliuretano producidas mediante esta composición de catalizador y método son útiles para material de tabla laminado, paneles de construcción, aislamiento de electrodomésticos y aislamiento aplicado con rocío.
