Abstract
Inorganic infrared attenuation agent blends have been developed to improve the thermal insulation properties of polymeric foams such as polystyrene low density foams. The inorganic infrared attenuation agent blends can include two or more metal oxides such as silicon dioxide, manganese (IV) oxide, iron (III) oxide, magnesium oxide, bismuth (III) oxide, cobalt oxide, zirconium (IV) oxide, molybdenum (III) oxide, titanium oxide, and calcium oxide. In some preferred embodiments, the inorganic infrared attenuation agent blends can include four or more of these metal oxides.
