The "PTC" characteristic, i.e., positive temperature coefficient effect, refers to a characteristic in which the resistivity of a material increases with an increase in temperature and increases sharply at a certain temperature interval. The temperature control heat tracing cable can be arbitrarily shortened or lengthened within a certain range for use. Namely, a self-temperature-limiting electric tracing band which can continuously generate heat is formed and can be cut at will. This structural form has the following disadvantages:
1. all insulating materials and outer layer sheath materials are polytetrafluoroethylene or polyolefin, and the material has low mechanical strength, so that the limitation of the use of the material is determined;
2. also because the material can cause fire when the temperature is too high (more than 280 ℃) to generate spontaneous combustion, the spontaneous combustion can be quickly and slowly carried out to the whole heating element.
