Product Overview
Low Voltage Black PET Heating Film is a flexible thin‑film heating element with black PET insulation surface. It adopts low‑voltage DC power supply (3.7V‑24V), with etched metal foil or carbon ink as heating circuit, sandwiched between two layers of black PET polyester film. It is a safe surface heating solution for low‑temperature scenarios, featuring concealed black appearance, uniform heating, ultra‑thin profile and high electrical safety.
Key Features
1. Low voltage safety: 3.7V/5V/12V/24V optional, low power consumption, no high‑voltage risk, suitable for consumer electronics and portable devices
2. Black matte appearance: opaque black PET substrate, beautiful and hidden, better thermal radiation effect
3. Ultra‑thin & flexible: thickness 0.12–0.2mm, bendable, fits curved and narrow mounting spaces
4. Even heat distribution, low thermal inertia, fast temperature rise
5. High dielectric insulation, stable performance, long service life
6. Customizable size, shape, power, voltage, with optional 3M PSA adhesive backing for easy installation
7. Max continuous working temperature: 80–105℃, suitable for low‑temperature constant heating
