Mica Heater Sheet

Mica Heater sheet, also known as mica heating film, is a flat electric heating element made by forming a resistance circuit from special metal foil (10–50 microns thick) and laminating it between two layers of mica insulation. The insulation material can be selected based on the required heating temperature and working environment. The size can be customized, ranging from a few square millimeters to several square meters.

Product Advantages

1. High Operating Temperature
High-temperature models of Mica Heater elements can reach up to 850°C, making them suitable for extreme thermal environments.

2. Surface Heating with High Efficiency and Energy Saving
As a flat surface heating element, Mica Heater film maximizes contact with the heated object, providing excellent heat transfer without an open flame. This results in thermal efficiency rates of around 90%, reducing heat loss and power consumption significantly.

3. Long Lifespan
Compared to traditional electric heating wire elements, mica heater sheets offer up to 10 times longer service life.

4. Flexible Shapes and Wide Applications
With a typical thickness of around 0.8mm, custom mica heaters can be made in various shapes and sizes, widely used in heating devices, curling irons, straighteners, heating cups, heating plates, medical care devices, instruments, and household appliances.

5. Safe and Flame-Free Heating
Mica heating film operates without open flames, ensuring safe usage even in close-contact applications. Low-voltage mica heating elements are safe for direct skin use, and voltage tolerance can reach up to 380V.

6. Strong Corrosion Resistance
With metal foil sealed within the mica insulation, the electric heater film resists chemical gases, liquids, and particle radiation, providing durable protection in harsh environments.

7. Integrated Circuit Control
The heating unit can be designed with built-in fast-heating circuits, insulation holding circuits, and temperature control circuits, enabling smart and automated thermal regulation.

8. Accurate Temperature Control and Low Thermal Inertia
The temperature control accuracy is within ±2%, offering quick response and precise performance.

9. Easy Installation and Wiring
Lead wires can be riveted onto the element, and the mica heating element can be fixed to the surface by adhesive or mechanical methods, making it adaptable to a wide range of use cases.
