LyTherm® 880-LH Binderless Grade Paper is a 100% inorganic material processed from washed, spun, high purity alumina-silica fibers. It is recommended for continuous use at temperatures up to 2600°F (1427°C) in applications where off-gassing of the organic binder cannot be tolerated. LyTherm® 880-LH Paper is manufactured using a patented process that provides high tensile handling strength. Because it is processed from higher alumina content fibers, LyTherm® 880-LH Paper has a higher use temperature, is less chemically reactive, and has lower thermal shrinkage. It is a clean, low shot content paper with extremely low thermal conductivity.
880-LH Papers are engineered primarily for applications in the heat treat industry above 2300ºF, where silica contamination, shrinkage, and tensile strength are problems. 880-LH Papers can be cut and handled without tearing, have a clean dust-free surface which eliminates metal pitting, and their binderless formulation prevents carbon pick up and surface discoloration.
LyTherm® 880-LH Binderless Paper possesses excellent chemical stability and resists attack from most corrosive agents. Exceptions are hydrofluoric and phosphoric acids and concentrated alkalies.
