Coliao Film Heater Pad 5V 1W
Polyimide heater film with a 5VDC power rating and 1W output provides compact heating for small areas. The film’s insulation contributes to safe operation, while its 80°C maximum temperature suits lightweight applications. A temperature controller is typically used to regulate heat since the film itself does not control temperature.
AIYUNNI High Temperature Tape
This polyimide film adhesive tape is designed for high-temperature applications, including 3D printing and electronics protection. Its silicone adhesive offers easy release without leaving residue. It withstands a broad temperature range from -73°C to 300°C, helping insulate nearby components from heat exposure.
Coliao Film Heater Pad 12V 7W
Operating at 12V with 7W output, this PI heating element reaches up to around 150°C. It uses polyimide insulation with a stable heating core and is designed for easy integration with a 12V temperature controller to maintain target temperatures without direct temperature regulation in the film itself.
Coliao Film Heater Pad 24V 30W (45mm x 100mm)
This larger 24V, 30W PI heater plate measures 45mm by 100mm, offering robust heat for broader surfaces. Like other polyimide heaters, it does not control temperature intrinsically and should be paired with a 24V temperature controller for stable operation over time. Its durable construction supports prolonged use with high insulation performance.
DWEII 24V 30W Film Heater Pad
This 24V, 30W film heater offers a sturdy 45mm x 100mm footprint. It features high dielectric strength and efficient thermal conduction. As with other polyimide heaters, temperature control is external, typically via a compatible 24V controller to achieve consistent heating across the target area.
MECCANIXITY 2.8W 5V PI Heater Pad
The MECCANIXITY heater film pack includes four 25mm x 20mm pads at 5V and 2.8W each. The package specifies a flexible polyimide layer with a thin metal heating element, designed for small, repeatable heating tasks. This option is suitable for experiments requiring compact heat sources with reliable insulation.
Buying Guide
Key considerations when selecting a polyimide film heater:
- Voltage and power: Choose a voltage that matches your controller and a power rating that produces the needed heat without oversizing the system.
- Size and footprint: Smaller pads fit tight spaces; larger pads cover more area but require more power management through a controller.
- Temperature range: Consider the maximum operating temperature and whether you need full control with a dedicated temperature controller.
- Control method: Most film heaters require external temperature control; ensure your controller can handle the heater’s characteristics and response time.
- Durability and insulation: Look for high insulation strength and heat resistance to extend service life in demanding environments.
- Adhesion and installation: Self-adhesive pads simplify mounting, but verify surface compatibility and cure considerations for long-term adhesion.
When assembling a heating solution, align the heater’s specifications with your project’s thermal needs, available power supply, and environmental constraints. For intricate or variable heating, a feedback loop using thermistors or temperature sensors provides more stable results than relying on the film alone.
