What is Kapton Film Flexible Heater?

A Kapton heater is a type of flexible, thin-film heating device made using Kapton, a polyimide film originally developed by DuPont. Kapton is renowned for its exceptional thermal stability, electrical insulation capabilities, and resistance to various chemicals. These properties make Kapton an ideal material for creating heaters used in diverse industrial and scientific scenarios.

Typically, the polyimide heater consist of a thin layer of Kapton film coated with a heating element, such as a resistive wire or a printed circuit. The heating element generates heat when an electrical current passes through it. Kapton’s impressive thermal stability enables these heaters to function at relatively high temperatures without degrading or sustaining damage.

How does Kapton Film Flexible Heater work?

The heaters operate on the principle of resistive heating, involving the following key components and processes:

Resistive Heating Element: At the heart of a film heater lies the resistive heating element. This component is typically crafted from a conductive material characterized by high electrical resistance, such as nichrome (a nickel-chromium alloy). This material is chosen for its proficiency in efficiently converting electrical energy into heat.

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.

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.

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.

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.
