TEMPMAX® ALUMINA FIBER BOARD / Polycrystalline Wool Board
TempMax® alumina fiber board is manufactured in a wet forming process using TempMax® alumina fiber bulk and binders. TempMax® alumina fiber board has excellent thermal stability at very high operating temperatures. TempMax® alumina fiber board can reduce energy costs and cycling times due to high insulating capability, as well as serving to protect refractory surfaces from thermal shock and chemical attack.
