Polyimide (PI) Heating Films, often referred to as film heaters, are thin, flexible, and lightweight electric heating elements. They are constructed using a high-temperature polyimide film as both the substrate and the overlay, with an etched-foil heating circuit encapsulated in between. This advanced design makes them ideal for applications requiring precise, reliable heat in a minimal space and under demanding conditions.

PTC heating elements are electric heating elements made of positive temperature coefficient (PTC) ceramic material. Their core features include automatic temperature regulation and over-temperature protection: At low temperatures, their resistance is low, allowing them to rapidly heat up upon power application. When the temperature reaches a specific critical point (the Curie temperature), their resistance increases dramatically, automatically reducing power consumption to avoid overheating. This adaptive feature ensures high safety and energy savings, enabling stable temperature control without the need for additional temperature control devices.

They are widely used in home appliances (such as air conditioning auxiliary heating and heaters), automotive electronics (seat heating and battery preheating), medical equipment, and industrial applications. Their compact design, long lifespan, and lack of open flames make them key components in modern intelligent thermal management solutions.

PTC (Positive Temperature Coefficient) air heaters are advanced electric heating devices built around PTC thermistor technology. Unlike traditional resistive heaters, their resistance increases exponentially with temperature, enabling self-regulating heat output that eliminates overheating risks.

The PTC insulated heater is a safe heating device that combines high-performance ceramic insulation material with a PTC (positive temperature coefficient) heating element. Its core feature is a double-insulated structure that completely isolates the heater from the external environment, effectively preventing the risk of leakage and complying with stringent electrical safety standards. The heater utilizes a self-regulating PTC chip, eliminating the need for an additional thermostat. It automatically reduces power as the temperature rises to avoid overheating. With its advantages of high-voltage resistance, breakdown resistance, high thermal efficiency, and long life, it is widely used in safe heating applications for medical equipment, household appliances, new energy vehicle battery packs, and industrial precision instruments. It is particularly irreplaceable in areas requiring strict insulation protection.
