Generally not. The melting point of conventional polypropylene non-woven fabric is 160~170 °C; and the non-woven fabric of styrene is about 260 °C.
However, there is a material which is made of acrylic fiber, viscose fiber or asphalt fiber by felting, felting, oxidized and carbonized, and then graphitized, and the carbon felt is high temperature resistant to 3000 ° C or higher. The coefficient of thermal expansion is less than (2~5)*10-6/°C, the strength is 3 times that of aluminum alloy, and the weight is only 1/5 of the steel. This material is used for aerospace, spacecraft, rocket nose cone, aircraft tail exhaust In the inner protective layer of the tube and the large-scale integrated circuit. The temperature resistance of the non-woven fabric ranges from 110 degrees to 3000 degrees, depending on what kind of non-woven fabric you use.
