に危険である。This type of PTC polymer can be used in temperature detectors, heating elements with a self-temperature control function, and the like. However, conventional PTC polymers have extremely insufficient thermal stability and antioxidant properties, and deteriorate when subjected to repeated heat cycles or exposed to oxygen, resulting in an increase in initial resistance and a decrease in mechanical properties. For example, if such a PTC polymer is used in a self-temperature-controlled heating element, if it is heated to a temperature above the peak point for some reason, it will lose its self-temperature control function and the current in the heating element will increase, eventually leading to burnout, which is extremely dangerous. is dangerous.
