Polyester Flexible Heaters
Polyester flexible heating elements guarantee a fast and uniform heat transfer. 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.
At a Glance: Polyester Flexible Heaters
- Polyester flexible heaters provide fast, uniform heat transfer for low-temperature applications, with operating temperatures ranging from -50°C to 95°C (203°F).
- Multiple heating technologies are available, including etched foil, wire wound, and ITO (indium titanium oxide) ink elements, allowing designs to be tailored to different power and performance requirements.
- Polyester heaters are commonly used in heated mirrors, battery warmers, de-icing systems, touchscreens, cabinet heaters, coffee machines, and other applications requiring thin, lightweight heating solutions.
Custom Designed for Your Unique Applications
Polyester flex heaters are used for low temperature applications. The maximum surface temperature for the polyester heater is 95°C (203°F). Polyester can be used with an etched foil element, a wire wound design, or with one of our ITO (indium titanium oxide) inks. With the ITO ink, the heat is generated by a number of parallel-connected ink resistors and, therefore, is very robust and insensitive to small damages.
The resistance is virtually constant up 100°C. The constant wattage polyester heaters, or mylar heaters, are mostly used in low power applications at moderate to high voltages and can be less costly than metal foil to get the same low power required. The resistance in the inks can be adjusted in the range from 50 ohm/sq. to 50 000 ohm/sq. and is therefore suitable for many different applications.
Etched Foil Polyester Heaters
Our etched foil polyester heaters offer lower wattage use, balanced heating output across the heater, edge loss compensation, and extremely thin designs. Overall heater size is limited by maximum element width (590 mm).
Wire Wound Polyester Heaters
Wire wound polyester heaters offer the capabilities of an etched foil heater without the strict size limitation. A fine nickel-chromium alloy wire is spiraled onto a center core of fiberglass producing a strong, flexible heating element.
Electronically-controlled precision winding equipment ensures consistency. Circuits are then hand-wound on permanent tooling, providing repeatability of resistance and pattern. Parallel circuits are utilized where possible, permitting continued operation should a single circuit be damaged.
Polyester Material Used for Flexible Heaters
Polyester material can be transparent, which can be beneficial when the flexible heater is in a light emitting environment such as a touchscreen panel or a light-backed user interface. Other typical applications for polyester heaters are heated mirrors, battery warmers, de-icing equipment, heated aquariums, coffee machines, cosmetic equipment, hand grip heaters, and cabinet heaters.

What are the advantages of polyester flexible heaters?
Polyester flexible heaters are designed to provide fast warm-up times and uniform heat distribution across the heated surface. The material supports efficient thermal transfer, which helps improve heating consistency and can contribute to longer heater life. Polyester heaters are also thin, lightweight, and adaptable to a wide range of low-temperature applications. Their design flexibility allows them to be configured with different heating element technologies to match specific performance requirements.
What heating element options are available for polyester heaters?
Polyester heaters can be manufactured using etched foil elements, wire-wound elements, or ITO (indium titanium oxide) ink technologies. ITO ink heaters generate heat through multiple parallel-connected ink resistors, making them resistant to small, localized damage. Etched foil heaters provide balanced heat output and edge-loss compensation in extremely thin designs. Wire wound heaters offer similar capabilities while accommodating larger sizes that may exceed etched foil heater width limitations.
What operating range can polyester flexible heaters support?
According to the source, polyester flexible heaters can operate from -50°C up to a maximum temperature of 95°C (203°F). They are available with voltages ranging from 1.0V to 400V and specific power outputs from 0.01W/cm² to 0.3W/cm². These characteristics make polyester heaters well suited for low-temperature heating applications. Optional pressure-sensitive adhesive (PSA) can also be incorporated for mounting purposes.
When should an etched foil polyester heater be selected instead of a wire wound heater?
Etched foil polyester heaters are typically selected when low wattage requirements, balanced heating performance, edge-loss compensation, and extremely thin constructions are important design considerations. However, etched foil designs are limited by a maximum element width of 590 mm. Wire-wound polyester heaters provide many of the same heating benefits while allowing larger overall heater sizes. The choice depends on application size constraints and heating requirements.
What applications commonly use polyester flexible heaters?
Polyester material can be manufactured with transparent properties, making it useful in light-emitting applications such as touchscreen panels and backlit user interfaces. Other applications identified in the source include heated mirrors, battery warmers, de-icing equipment, heated aquariums, coffee machines, cosmetic equipment, hand grip heaters, and cabinet heaters. The material's flexibility and low-temperature operating characteristics make it suitable for a broad range of commercial and industrial products.
