Ceramic Fiber Paper

Ceramic fiber paper consists primarily of high purity alumino-silicate fiber and is made through a fiber washing process. It offers high temperature resistance, very low thermal conductivity, chemical corrosion resistance and thermal shock stability.

Features:

Easy to wrap, shape or cut

Lightweight

Low thermal conductivity; Low heat storage

Good uniformity and smooth appearance

Good flexibility and toughness and resistance to erosion

Good dielectric strength and sound insulation

Excellent thermal shock resistance

Excellent chemical stability and machining property

Excellent corrosion resistance
