Polyester heater uses pet polymer as insulated layer. This material offers many design features 

such as excellent dielectric strength in very thin cross sections. PET heaters can be 

customized to any size,shape and wattages as your requirements.


PET electric heating film 

 The PET electric heating film is a low-temperature metal electric heating film which takes a PET polyester film as an insulating layer; and the PET polyester film has excellent insulating strength, can be bent (for example, the film can be wound outside a drum-shaped object to be heated), and has excellent dielectric strength and rather high thermal conversion efficiency which is usually 95 percent or so.


Technical Parameters
Insulating MaterialPET Polyester Film
Common Thickness0.1~0.6mm
Maximum Service Temperature100°C (below 80°C for a long time)
Minimum Temperature-36°C
Maximum Power Density7.8W/cm2

Main characteristics
A: The PET electric heating film is a flexible heating element and can be bent.
B: It is energy-saving and power-saving. The temperature that a general heating material reaches at 10W can be reached by the metal electric heating film at 7-8W, and the energy is saved by about 30 percent.
C: The metal electric heating element has long service life which is more than 5 times that of the traditional electric heating wire heating element.
D: The product has no open fire and is safe and reliable. A low-voltage electric heating appliance produced by using the pet electric heating film can be used next to the skin, is safe and reliable, and cannot cause electric shock hazard.

More Information of polyester

Polyester allows heated elements to have superior heat transfer and exceptionally uniform heat output, which results in a faster warm-up cycle and longer life. Also known as Mylar heater, this can be used to cover large areas with even heat on flat or gently curved surfaces. Polyester can be used with an etched foil or with one of our popular printed polymers.

Etched foil polyester heaters can be designed and fabricated in many types of configurations to fit the size and shape required in your application.

One of our printed polymers is a constant wattage circuit based on low resistance printed silver as the current distributor. The heat is generated by a number of parallel-connected polymer resistors and is therefore very robust and insensitive to small damages. The resistance is virtually constant up 100°C. The constant wattage polymer heaters or mylar heaters are mostly used in low power applications at moderate to high voltage, and can be less costly than metal foil to get the same low power required. The resistance in the polymer can be adjusted in the range from 50 ohm/sq to 50 000 ohm/sq and is therefore suitable for many different applications.

The other printed polymer functions as a PTC circuit also based on low resistance printed silver as a current distributor. The heat is generated by a number of parallel connected polymer resistors with PTC characteristics (Positive Temperature Coefficient). In most cases the polymer resistor is covering the polyester heater completely and hence gives a very even temperature distribution. The PTC effect makes the heater self-limiting and hence hot and cold spots are avoided as the power is generated were you need it.

The printed polymer heaters are also more corrosion resistance than metal heaters.
