Ceramic fiber papers are made of ceramic fiber and a small amount of binder. The fiber is evenly distributed and the binder will burn off completely during using.
Due to different operating temperatures, it is divided into four types of materials, standard, high aluminum, and zirconium-containing ceramic fiber paper (236/436/536).
1.Low heat capacity;
2.Low thermal conductivity;
3.High strength;
4.High tensile strength;
5.Low slag ball conten;
6.Excellent electrical insulation ability and mechanical processing performance.
Fireproof: Retains full shape and size after a major fire.
High temperature resistance: There are two types of temperature resistance: 1260 and 1400 °C.
Heat insulation: It can effectively prevent or slow down heat transfer, and the thermal conductivity can be as low as 0.12w/(m.k) at 800°C.
Insulation: Inorganic silicate material, high temperature non-conductive.
Sound insulation: high noise reduction coefficient.
Sealing: It has certain elasticity and can be used for high temperature sealing.
Ceramic fiber papers are widely used in building materials, metallurgy, glass and other industries, but also used in the automobile industry, instrument equipment, electric insulation, can also be used to manufacture gaskets.
