Ceramic Fiber Paper

JIUQIANG ceramic fiber paper is manufactured from high-grade ceramic fiber with low slag ball content, and formed into excellent flexible sheet through unique beating, deslagging, slurry-compounding, long net forming, vacuum water removal, drying, cutting and rolling processes.

  It is featured with high temperature resistance and heat insulation and high anti-melt capability, very low thermal conductivity, chemical corrosion resistance and thermal shock stability.
   So the paper can be widely used in building, glass industry for teeming pads separation. It provides maximum heat resistance and thermal insulation in limited space.

 Low thermal conductivity; Low heat storage
Contains no asbesto and anticorrosion

Good uniformity and smooth appearance

Good flexibility and toughness and resistance to avulsion

Good dielectric strength and sound insulation

 Excellent thermal shock resistance
Excellent chemical satability and machining property

Excellent corrosion resistance
