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.
