LyTherm® Rollboard Paper is a lightweight refractory material processed from a blend of high purity alumina-silica fibers into a highly flexible, uniform sheet. It is recommended for continuous use at temperatures up to 2300°F (1260ºC).
LyTherm® Rollboard is a low cost, utility grade paper that has low shrinkage, good handling strength, and low thermal conductivity. It contains a small amount of organic binder for processing which makes it flexible, yet reduces off-gassing and odor during use. LyTherm® Rollboard has a highly uniform structure due to its controlled basis weight and thickness, assuring homogeneous thermal conductivity and a clean, smooth surface ideal for gasketing or sealing.
LyTherm® Rollboard is completely free of asbestos and is designed to be an economic replacement for asbestos paper in most applications. LyTherm® Rollboard is easy to handle and is readily cut with a knife, shears, or standard steel rule dies. Its flexibility allows it to be wrapped or rolled to fit most comlex configurations.
