폴리스티렌 저밀도 발포체와 같은 중합체성 발포체의 단열 특성을 개선시키기 위해 무기 적외선 감쇠제 블렌드가 개발되었다. 무기 적외선 감쇠제 블렌드는 이산화규소, 산화 망간 (IV), 산화 철 (III), 산화 마그네슘, 산화 비스무트 (III), 산화 코발트, 산화 지르코늄 (IV), 산화 몰리브덴 (III), 산화 티타늄, 및 산화 칼슘과 같은 2 개 이상의 금속 산화물을 포함할 수 있다. 일부 바람직한 구현예에서, 무기 적외선 감쇠제 블렌드는 이들 금속 산화물 중 4 개 이상을 포함할 수 있다. 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.
