LyTherm Ceramic Rollboard Paper

1/16" x 24" x 200' LyTherm Ceramic Rollboard Paper
Product Code: SGI-310-0490

LyTherm®Rollboard paper is a lightweight refractory material processed from ablend of high purity alumina-silica fibers into a highly flexible, uniform insulationmedia. It is recommended for continuous use at temperatures up to 2300°F(1260°C).

LyTherm® Rollboard is a utility grade paper that has low shrinkage, good handlingstrength, and low thermal conductivity. It contains a small amount of organicbinder for processing, which makes it flexible, yet reduces off gassing and odorduring use. It’s flexibility allows it to be wrapped or rolled to fit most complexconfigurations.
