LEPE fiber board has great anti-mechanical-destruction capacity, and can be applied as materials which require tenacity, self supporting ability, and thermal insulation ability. More specifically, it can be used as : thermal insulation lining and back lining in pusher kilns, ladle furnaces, bell-cover kilns, tunnel kilns, roller kilns, and aluminum melting kilns, and thermal treatment furnaces; high-temperature fire damper board and thermal insulation for kiln cars; thermal insulation for various high-temperature industrial kilns and furnaces.
