LyTherm® 3000-L alumina paper is a lightweight refractory material processed from high purity bulk alumina fibers formed into a flexible sheet. It is recommended for continuous use at temperatures up to 3000°F (1650°C), in applications that demand low shrinkage, a high degree of thermal stability, and temperature protection up to 3000°F (1650°C).
LyTherm® 3000-L is designed specifically for use in high temperature heat treating, ceramic kilns, and in aerospace insulation composites.
LyTherm® 3000-L Alumina Paper contains an organic binder to provide increased handling strength at room temperature. It possesses excellent chemical stability and resists both oxidation and reduction, even in the presence of hydrogen at high temperatures. If it becomes wet due to water, steam, or oil, its thermal and physical properties will return upon drying.
