1. Kapton Film: The resistive heating element is either sandwiched within or printed onto a slim, pliable Kapton film. Kapton proves to be an excellent choice for this application due to its polyimide composition, which grants it remarkable resistance to high temperatures. It can withstand the heat generated during operation without deteriorating.

2. Electrical Current: When an electrical current is supplied to the resistive heating element, it opposes the flow of electrons. Following Joule’s law of heating, this resistance prompts the resistive element to generate heat. The amount of heat generated is directly proportional to the electrical current passing through the element and the square of the current’s magnitude.

3. Heat Distribution: The heat produced within the resistive element is subsequently distributed across the surface of the Kapton film. Kapton is an efficient thermal insulator, allowing it to preserve and evenly disperse the heat. This uniform distribution of heat is crucial for maintaining consistent temperatures within the intended application.

4.Temperature Control: Precise temperature control of the heating element is achievable by regulating the electrical current flowing through the resistive element. By adjusting the current’s intensity, the heater’s temperature can be raised or lowered, facilitating accurate temperature control across a range of applications.
