LyTherm® 1530-L premium grade paper is a lightweight refractory material processed from highly washed, spun, high purity alumina-silica fibers formed into a highly flexible sheet. It is recommended for continuous use at temperature up to 2300°F (1260°C) in applications requiring high strength, resiliency, and excellent thermal properties.
Because it is formulated with a low content of unfiberized particles, LyTherm® 1530 offers an extremely low thermal conductivity and a dust-free surface. It was designed specifically for applications where low shot content, compression recovery, low thermal conductivity, and minimum shrinkage are of critical importance.
