What is the difference between ultra-thin flexible film heating element and PTC heating element heater?

What is the difference between ultra-thin flexible film heating element and PTC heating element heater?

There are several main differences between ultra-thin flexible film heating element and PTC heating element heaters, as shown in the table below:

Project classification PTC heater ultra-thin flexible film heating element

Surge current Yes, no

Power (watts) High power applications Low power applications

Ohm's law is not true

Heating air heating and conduction heating conduction heating

The constant temperature voltage change has little effect on the temperature and power (W) of the heater. The voltage change will affect the temperature and power (W) of the heater

However, if low power is maintained (<150 ℃), the temperature will remain consistent at a stable heat dissipation rate

Power control cannot control the exact wattage of the heater. The wattage will vary according to the ambient temperature and heat dissipation rate, and the heater power will not change with the surrounding environment

Advantages: Stable temperature; Safe use; Widely applicable, lightweight, compact, and flexible; Widely applicable

What should I know before installing the ultra-thin flexible film heating element?

Please carefully read the following content before installing the ultra-thin flexible film heating element to prevent misoperation and ensure a longer heater lifespan.

Do not let the leads hang loosely. Ensure that the leads are installed in a fixed position to prevent pulling the leads from causing the flexible film heating element heater to break.

Do not immerse the flexible film heating element heater in liquid or expose the heater to steam and corrosive gases.

Do not operate the heater at a voltage higher than the specified or rated voltage.

Do not cut, drill holes, disassemble heaters, or attempt to repair damaged heaters and avoid contact with sharp objects. The damaged flexible film heating element heater will be unusable.

Do not operate the heater unattended unless sufficient control devices are installed to ensure safety.

Do not overlap the flexible film heating element heater.

Do not attempt to repair damaged flexible film heating element heaters.
