Glass wool felt belongs to thermal insulation material, not refractory material. Because the limit temperature of glass wool felt is about 450 degrees Celsius, the melting temperature is 600 degrees Celsius, and the general flame temperature is as high as 600 degrees Celsius or above. Therefore, glass wool felt is only a kind of medium and low temperature insulation material. Refractory materials mainly refer to inorganic nonmetallic materials such as ceramic fiber blanket and aluminum silicate needle-punched blanket, and the fire resistance grade of ceramic fiber aluminum silicate products is between 850- 1400 degrees Celsius. If the questioner wants to choose refractory materials, try to choose ceramic fiber aluminum silicate materials.
