Industrial Furnaces Ceramic Fiber Modules Light Weight Insulation 1260℃ Standard
Product Description
Characteristics
Excellent chemical stability, excellent thermal stability, low thermal conductivity, low heat capacity
Excellent elasticity, because the fiber is in a pre-compressed state, its expansion can compensate for fiber shrinkage and improve the thermal insulation performance of the fiber lining.
Application
Metallurgy, machinery, building materials, petrochemical, non-ferrous metals and other industries, industrial furnaces, heating equipment lining
