4210HA Ceramic Fiber Paper Descripion:
1.Ceramic fiber paper is manufactured from high grade ceramic fiber with low slag ball content, and formed into excellent flexible sheet through unique beating, des-lagging, slurry compounding, long net forming, vacuum water removal, drying, cutting and rolling processes.
2.It is featured with high temperature resistance and heat insulation and high antimelt capability, very low thermal conductivity, chemical corrosion resistance and thermal shock stability.
3.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.
4210HA Ceramic Fiber Paper Applications:
1.Industrial furnace, Heat treatment, High temperature pipe.
2.Insulating materials of boiler, turbine and nuclear power.
3.Insulating material for face and top of industrial furnaces and heating device.
4.Excellent sound insulation for Construction Fire protection.
5.High temperature filter material for nonferrous metal.
4210HA Ceramic Fiber Paper Advantage:
1.Low thermal conductivity heat storage and heat capacity.
2.Excellent heat insulation.
3.Excellent chemical stability.
4.Shock and chemical attack resistant.
5.Low thermal conductivity and shrinkage.
6.Resilience under working condition, low shrinkage under high temperature.
7.Excellent sound insulation and resistance of folding.
