Industry Furnace Polycrystalline Wool Alumina Fiber Board

Product Description

TEMPMAX^® Thermal Insulation Polycrystalline Wool Alumina Fiber Board / PCW 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.
