Coliao 5V 1W Film Heater Plate

Product overview: Coliao’s 6-piece adhesive film heater set uses polyimide film outside with a thermo foil heating element inside. Operating at 5V with 1W power, the maximum temperature reaches about 80°C. It is designed for use with a 12V temperature controller, since the film itself does not regulate temperature. The kit emphasizes fast preheating, stable interior temperatures, and high insulation strength for safe operation.
Key features: Polyimide heater film, 5V operation, 1W power, approximate 80°C max temperature; stable operation when paired with a controller; strong heat resistance and long service life.
Coliao 12V 7W Film Heater Plate (25×50 mm)

Product overview: This Coliao heater plate runs at 12V with 7W output, reaching approximately 150°C. It utilizes polyimide film as an outer insulator and a thermo foil heater inside. It is intended for use with a 12V temperature controller. The design emphasizes fast preheating, temperature stability once at operating temperature, and durable insulation for long service life.
Key features: 12V, 7W, 25×50 mm; high-temperature capabilities; stable operation with external controller; durable, insulated construction.
Coliao 24V 30W Film Heater Plate (45×100 mm)

Product overview: This larger Coliao heater plate operates at 24V and provides 30W, reaching around 170°C. It’s designed for fixed-temperature operation with a 24V controller. The device uses a polyimide outer layer and a thermo foil inner heater, ensuring fast preheating and stable temperatures during operation while maintaining strong insulation and safety.
Key features: 24V, 30W, 45×100 mm; high maximum temperature; suitable for applications needing substantial heat in confined spaces; reliable insulation and longevity.
DWEII 12V 30W Film Heater Plate

Product overview: The DWEII 12V model delivers 30W with a 12V supply, capable of reaching up to about 170°C. It emphasizes excellent dielectric strength, thermal conductivity, and resistance stability. Like other film heaters, it is designed to be used with a temperature controller to manage heat output and maintain desired temperatures. The adhesive plate design allows easy mounting on surfaces.
Key features: 12V, 30W, 45×100 mm; high-temperature capability; strong electrical insulation; compatibility with 24V or 12V controllers depending on setup.
Buying Guide: Key Purchase Considerations
- Voltage and power: Choose a heater that matches your system voltage (5V, 12V, or 24V) and provides enough wattage to reach the needed temperature within your design constraints.
- Size and form factor: Consider the footprint (mm) and thickness to fit tight spaces. Larger plates deliver more heat but may require better heat sinking or airflow.
- Temperature target and control: Polyimide film heaters do not regulate temperature on their own. Ensure you have an appropriate temperature controller or thermistor/probe to maintain stable results.
- Material durability: Look for high-quality polyimide film with strong insulation and good resistance to temperature cycling for longevity in fluctuating environments.
- Installation and mounting: Adhesive-backed designs simplify mounting but verify surface compatibility and adhesion strength for your application.
- Safety considerations: Ensure proper wiring, avoidance of short circuits, and use with protective enclosures or shields if operating near sensitive components or flammable materials.
- Application scope: For electronics, 3D printing beds, or small appliances, select a model with the right temperature range and heat distribution to meet application needs.
- Maintenance and replacement: Consider availability of replacement pads or compatible temperature controllers to extend service life and reduce downtime.
These product options provide a range of voltages and sizes suitable for various hobbyist and light-industrial uses. When selecting a polyimide film heater, align the device’s electrical requirements with your controller capabilities, then evaluate the area sealing, insulation quality, and mounting method to ensure reliable, long-term performance.
