DKJL Ceramic Fiber Board

DKJL ceramic fiber board is manufactured through a wet-forming process using bulk fibers and binders. Ceramic fiber board is designed for insulation applications experiencing vibration, mechanical stress, and erosive forces. Ceramic fiber board can reduce energy costs and cycling times due to its high insulating capability, as well as serve to protect refractory surfaces from thermal shock and chemical attack.
