Its softening point approaches 1700 oC and can be used at 900oC for a long time. 
It has fine chemical satiability and favorable upright electricity.
This fabric is applicable for use as a heat-resistant, fire-resistant and corrosion-resistant material 
in the construction of rockets, missiles, and other space vehicles. 
Apart from applications requiring high temperature-resistance,it is also has insulation and fire prevention uses.
With resistance to temperatures up to approximately 1000 oC, this fabric is used for the production of 
fireproof protective mats, fireproof curtains and fire blankets. 
It is also used as protective material for welding, a filter for molten metal, for dust collection 
in high temperature gas media, and filtration in high temperature liquids etc.
