ZAL-45 is a high-density board that exhibits a fine, open-pore structure resulting in a unique combination of high strength and low thermal conductivity. ZAL-45 exhibits very good dimensional stability to 1650°C (3000°F) with intermittent use to 1700°C (3192°F).
ZAL-45AA is a high-density high-strength, alumina-bonded product with superior resistance to chemical attack along with good dimensional stability in industrial applications with continuous temperatures of 1550°C (2822°F) with intermittent use to 1600°C (2912°F).
ALC-AA is an Al2O3-bonded, uniformly-bound, low-density cylindrical shaped insulation with very useful properties in applications with corrosive and reducing conditions and continuous operating temperatures to 1500°C (2732°F).
CRYSTAL-18 insulating boards, cylinders and custom shapes exhibit low thermal conductivity, good strength, superior thermal shock resistance and high dimensional stability in applications with continuous temperatures to 1550°C (2822°F).
ECO-20AA is an ultra-high-alumina utility-grade board that is useful in furnaces with reducing atmospheres with temperatures as high as 1600°C (2912°F) and is also useful in non-ferrous metal applications where SiO2 cannot be tolerated.
ZAL-15 is an engineered low-density structure exhibiting very good hot strength and dimensional stability in industrial applications with continuous operating temperatures to 1550°C (2822°F) – withstanding intermittent use to 1650°C (3002°F).
ZAL-15AA is an alumina-bonded, low-density structure with very good hot strength and dimensional stability in corrosive industrial applications involving continuous operating temperatures to 1500°C (2732°F) – withstanding intermittent use to 1600°C (2912°F).
