Fireproof Insulation Board

Fireproof insulation board is a kind of refractory ceramic fiber. It is also called refractory insulation board, which is fire-proof and thermal-insulated. Beside the properties above, such refractory board is featured with low thermal capacity and conductivity, good thermal shock resistance, good tensile strength, excellent chemical stability, acid and alkali resistance. So, it is extensively used in the high temp or insulation parts.applications of insulation board
