Product description of ceramic fiber blanket
Ceramic fiber blanket is mainly divided into ceramic fiber blowing blanket and ceramic fiber spinning blanket. Ceramic fiber spinning blanket is superior to ceramic fiber blowing blanket in thermal insulation performance due to its long fiber and small thermal conductivity. Most thermal insulation pipes are constructed with ceramic fiber spinning blanket.
Features of ceramic fiber blanket
Ceramic fiber blanket can maintain good tensile strength, toughness and fiber structure when it is used in neutral and oxidizing atmosphere for a long time. The temperature resistance is 950-1400 ℃.
