How Mica Heaters Work

Mica heaters consist of a nickel-chromium resistance element encapsulated between layers of high-grade mica insulation and enclosed within a durable stainless steel sheath. The mica provides excellent electrical insulation while allowing efficient transfer of heat to the heated component. Their compact construction makes mica heaters particularly suitable where installation space is limited and fast, uniform surface heating is required.

Typical Mica Heater Applications

Mica heaters are suitable for low to medium temperature industrial heating applications, including extruder and injection moulding machine barrels and dies, co-extruders, material transfer pipes and other process equipment requiring compact surface heating.

They can be manufactured as flat plates in a wide range of shapes, wrap-around bands in single, two-piece or multi-segment configurations, and L- or U-shaped heaters. Backing and clamping plates can also be incorporated where required to help maintain close contact with the heated surface.

Mica heaters are suitable for continuous operation at temperatures up to 250°C (482°F), with occasional operation up to 300°C (572°F).
