In compact devices, traditional rigid heaters add unnecessary bulk and weight. A stretchable flexible heater made from TPU film provides an ultra-thin, conformable heating element that bonds directly to curved or flat surfaces for maximum thermal efficiency.
Hochuen’s TPU film heater integrates a printed silver-resin and carbon conductive circuit, delivering fast thermal response and low-voltage performance for demanding environments.

Why Choose a TPU Flexible Heating Element?
- Ultra-Thin & Lightweight: At ≤ 0.2 mm, this thin film heater fits tight enclosures and weight-sensitive assemblies without sacrificing performance.
- Fast Thermal Response: Low thermal mass ensures rapid heat transfer, ideal for active, responsive temperature control.
- Low-Voltage Operation: Standard 8V 12W low voltage film heater design seamlessly integrates into portable and battery-powered products.
- Flexible & Conformable: TPU substrate easily adheres to irregular, cylindrical, or flat surfaces using high-temperature adhesive options (e.g., 3M 467/468).
Typical Applications
- Medical Device Flexible Heater: Stable surface heating for clinical instruments and wearable diagnostics.
- Anti-Fog & Anti-Condensation: Clear heating elements for outdoor electronics, cameras, optical sensors, and displays.
- Industrial & Aerospace: Compact heating layer for cold-environment automation and enclosure warming.
