LyTherm 970-LK Paper

1/4" x 60" x 190' LyTherm 970-LK Paper
Product Code: SGI-310-0275

LyTherm® 970-LK commercial grade paper is a lightweight refractory material processedfrom washed, spun, high purity alumina-silica fibers formed into a highly flexiblesheet. It is recommended for continuous use at temperatures up to 2300°F (1260°C) inapplications where insulating efficiency and high strength are important.
