LyTherm® 970-L Commercial grade paper is processed from washed, spun, high purity alumina-silica fibers formed into a highly flexible sheet. It is recommended for continuous use at temperatures up to 2300° F (1260° C) in applications where insulating efficiency and high strength are important.
Because it is processed from washed fiber, LyTherm® 970-L paper is clean, has low shot content, and offers low thermal conductivity. It’s highly uniform structure assures homogeneous thermal conductivity throughout, and its high tensile strength makes it ideal as a gasket, seal, or spacer material.
LyTherm® 970-L Commercial Paper contains an organic binder to provide increased handling strength at room temperature. It possesses excellent chemical stability and resists attack from most corrosive agents. Exceptions are hydrofluoric and phosphoric acids and concentrated alkalis. Because of its high-purity chemistry, LyTherm® 970-L Commercial paper resists both oxidation and reduction. If it becomes wet due to water, steam, or oil, its thermal and physical properties will return upon drying.
