High temperature fire sleeves with high and low-temperature resistance, flame retardant, voltage resistance, ozone resistance and arc resistance, are widely used in aerospace.

The high-temperature environment experienced by aircraft is caused by aerodynamic heating, engine gas and solar radiation in space. The aircraft flies in the air for a long time, and some flight speeds are as high as 3 times the speed of sound. The high-temperature aerospace thermal insulation materials used should have good high-temperature endurance strength, creep strength and thermal fatigue strength, high oxidation resistance and thermal corrosion resistance in air and corrosive medium, and should have the stability of organizational structure working at high temperature for a long time. QIAN-ZE thermal insulation products has characteristics of high and low temperature resistance, corrosion resistance and aging resistance, which are widely used in aerospace.
