LyTherm® 970-LH Binderless Grade Paper is a 100% inorganic material, and is manufactured using a patented process that provides high tensile handling strength. Because it is processed from washed, spun, high purity alumina-silica fibers, LyTherm® 970-LH Paper is clean, has low shot content and offers low thermal conductivity. It is recommended for continuous use at temperatures up to 2300°F (1260°C) in applications where off-gassing of the organic binder cannot be tolerated.
970-LH Papers are engineered primarily for applications in the heat treat industry, where its high strength allows it to be cut and handled without tearing, its low shot content eliminates metal pitting, and its binderless formulation prevents carbon pick up and surface discoloration. Because it contains no organic binders, 970-LH Paper does not off-gas or release carbon particles into the furnace environment. When used as a separator, 970-LH Paper prevents parts from sticking, and reduces contamination pick up from metal trays, or allows the use of lower cost graphite hearth plates. LyTherm® 970-LH Binderless Paper possesses excellent chemical stability and resists attack from most corrosive agents. Because of its high purity chemistry, LyTherm® 970-LH Paper resists both oxidation and reduction.
