Product Description

Laurel ceramic fiber paper, is a lightweight refractory material processed from a blend of high purity alumina-silica fibers into a highly flexible, uniform sheet.
Ceramic fiber paper, 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 odour during use. our product has a highly uniform structure due to its controlled basis weight and thickness, assuring homoaeneous thermal conductivity and a clean, smooth surface ideal for gasketing or sealing.
Ceramic fiber paper is completely free to asbestos and is designed to be an economic replacement for asbestos paper in most applications.

Applications

1.Die cut gaskets between castings in coke oven doors, blast furnace hot air piping, aluminium heat treating furnace, tuyeres and heat treat furnaces.
2.Backup for brick and monolithic refractories in blast furnace stoves, piping, tundish, ladle, hot metal cars, trough etc.
3.Mould wrapping for controlled cooling
4.SEN insulation wrapping
5.Shield for welding & brazing operation
6.Rotary kiln back-up insulation
7.Fabricated into tap out cones for Aluminium industry.
8.Strips in bottom of ingot mould for sealing
