LJ 1400 Fiber Board

Characteristics

High stability; Low thermal conductivity; Low thermal capacity; Resistance to thermal shock; Resistance toerosion; Easy to bo processed and cut; High thickness precision and size precision; Exceptional ability towithstand flames and gas flows; Easy to install and convenient to use.

Application

The board has great anti-mechanical-destruction capacity, and can be applied as materialswhich requiretenacity, self supporting ability, and thermal insulation ability. More specifically, it can be used as:thermalinsulation lining and back lining in pusher kilns, ladle furnaces,bell-cover kilns, tunnel kilns, oller kilns, andaluminium melting kins,and thermal treatment furnaces;High-temperature fire damper board and thermal insulationfor kiln cars;Thermal insulation for various high-temperature industrial kins and furnaces.
