Advantages of PTC heating film

1. Insulation withstand voltage, leakage current and insulation resistance are excellent and stable.

2. Long service life. The service life of electrothermal film electrothermal element is 10 times longer than that of traditional electrothermal wire electrothermal element. 　　　　

3. Compared with the traditional electric heating wire heater, it can be dry-fired.

4.PTC has a small volume and a small area for constant temperature heating. Using PTC heater can save the parts of temperature control and over-temperature protection.

5. In the occasion of medium and small power heating, PTC heating element has the advantages of constant temperature heating, no open flame, high heat conversion rate and little influence by power supply voltage.
