Ceramic fiber felt

Product category:
● 1000 ceramic fiber felt
● 1260 ceramic fiber felt
● 1400 ceramic fiber felt
Product Description:
● ceramic fiber felt is made of ceramic fiber cotton produced by resistance melting and blowing fiber forming process as raw material and made by vacuum forming process.
● ceramic fiber felt is a lightweight and flexible refractory fiber thermal insulation material, which is composed of high-purity refractory oxide and organic binder.
● ceramic fiber felt is a multifunctional product with good strength and elasticity in addition to the excellent performance corresponding to bulk ceramic fiber cotton. It is suitable for expansion joints and high temperature gaskets of kiln and boiler walls. When used as gasket, its good resistance to molten metal penetration is suitable for ingot base plate sealing, plug core gasket and aluminum billet casting gasket.
Product features:
● low thermal conductivity, low thermal capacity
● excellent chemical stability
● excellent thermal stability and thermal shock resistance
● excellent sound absorption
● soft and elastic
● easy to construct, cut and process
