Polyimide tape is generally non-flammable. This is mainly due to the inherent properties of the polyimide material, which offers excellent high-temperature resistance. Its decomposition temperature is very high, meaning it does not easily reach the decomposition point or ignite within conventional operating temperature ranges. In scenarios with extremely stringent fire safety requirements, such as the nuclear industry, polyimide tape performs reliably. Even under high-temperature conditions — for example, localized high-temperature zones around nuclear reactors — it maintains its structural and chemical stability. It does not burn rapidly as temperatures rise, providing reliable protection for the safe operation of nuclear facilities. Moreover, during the manufacturing process, flame-retardant components may be added to further enhance the tape's flame resistance. These components help inhibit the initiation and spread of combustion, reducing fire risks. However, although polyimide tape is non-flammable under normal conditions, the possibility of combustion cannot be completely ruled out in extreme situations, such as prolonged direct exposure to open flames or abnormally high temperatures
