The K Shield BF paper was designed specifically for vacuum furnaces. An inorganic paper with stronger fibers than other papers on the market. It does not flake or disintegrate during cycles keeping materials out of filter systems enabling furnaces to achieve better performance and less down time from cleaning filter systems. Depending on the application, multiple uses of the K Shield BF paper may be possible leading to a significant cost savings. When the time comes to repair or reline furnaces Lynn Manufacturing has a full range of high temperature insulating, gasketing, and repair materials in stock.
