KToyeang 11 Gauge High Temperature Wire 16.4Ft
This mica-insulated cable uses mica tape, fiberglass braid, and stranded oxygen-free copper to achieve rated performance from -76°F to 932°F (working up to 500°C). The product lists an 11 AWG conductor, 16.4 feet of length, and rated voltages of 300V/500V. The multi-layer wrapping offers improved resistance to heat, wear, and fire compared with common PVC or silicone cords.
Typical applications include electric heaters, kilns, ovens, and motors where insulation must withstand sustained high temperatures. The thicker 11 AWG core supports higher current loads, making it suitable for medium- to high-power heating elements or power leads in high-temperature assemblies.
KToyeang 18 Gauge 2 Conductor High Temperature Wire 25Ft
This 2-conductor mica and fiberglass insulated cable is specified for -76°F to 932°F operation, with a rated temperature of 752°F and an overall diameter measuring approximately 6.2 x 4.0 mm. The 18 AWG paired conductors are wound with glass fiber braid and fluoroglovite tape for multi-layer insulation.

Because it is a two-core cable, this product is suited to wiring element leads, lamp holders, or small heating circuits inside ovens and boilers where two-conductor routing simplifies installation. The 25-foot length provides flexibility for routing through equipment or retrofitting older appliances.
YeloDeer 10 AWG Mica High Temperature Wire (10 FT)
YeloDeer offers mica-insulated wires in multiple gauges including 10 AWG, which has larger conductor area for higher current capability. Insulation materials include mica and glass fiber to prevent insulation melting or carbonization at high temperatures.
Available lengths and gauge options make this product adaptable to both high-power heater connections and smaller element leads. The thicker 10 AWG variant is intended for applications requiring greater current capacity like large heating elements or supply leads inside industrial heating equipment.
Coliao 45mmx100mm Film Heater Plate Adhesive Pad (24V 30W)
This polyimide (PI) film heater is a flexible adhesive strip rated at DC 24V and 30W, with a maximum surface temperature around 170°C. The heating element uses thermo foil embedded within polyimide insulation to create a thin, conformable heat source suitable for localized heating.

Film heaters are commonly used on flat or curved surfaces such as instrument housings, molds, or localized process heating. Note that film heaters typically need an external temperature controller or thermostat for closed-loop temperature control, as they do not self-regulate.
XIITIA 15pcs 45mmx100mm Film Heater Plate Adhesive Pad (24V 30W)
The XIITIA kit bundles 15 polyimide film heaters of the 45 x 100 mm size, rated at 24V DC and 30W. These flexible, lightweight strips provide rapid surface heating and are noted for good dielectric strength and thermal conductivity efficiency.
Because these heaters are sold in multi-packs, they are useful for batch installations, prototyping, or replacement applications across multiple devices. As with other PI film heaters, temperature control requires external electronics such as a 24V controller or thermostat to avoid overheating.
Buying Guide: Choosing The Right Mica Strip Heater Or Mica Insulated Component
Selecting a mica strip heater or mica-insulated heating component depends on application temperature, geometry, electrical load, and control strategy. Below are key considerations and comparison perspectives to guide matching product to need.
Temperature Rating And Continuous Service
- Maximum Operating Temperature: Verify the continuous working temperature vs peak temperature. Mica-insulated wires often list working ranges up to 932°F (500°C). Film heaters (PI) typically operate at lower surface temps (100–170°C).
- Rated Temperature vs Short-Term Peaks: Ensure insulation and conductor materials are rated for expected sustained load and intermittent spikes.
Electrical Requirements
- Wire Gauge And Current Capacity: Choose conductor gauges (e.g., 10 AWG, 11 AWG, 18 AWG) based on expected current. Thicker AWG (numerically smaller) carries more current.
- Voltage Rating: Match cable or heater voltage to supply. Film heaters are often low-voltage DC (24V), while mica-insulated wires are rated for higher voltages (300–500V).
Form Factor And Mounting
- Strip/Film Heaters: Use when a thin, conformal heat source is needed for direct surface application. Adhesive-backed PI films are suitable for flat surfaces or light curvature.
- Mica-Insulated Wires: Use when routing high-temperature power leads within ovens, kilns, or heating elements where a robust, high-temp cable is required.
Durability And Environmental Resistance
- Fire And Wear Resistance: Mica and glass fiber braids improve abrasion and fire resistance relative to organic insulations.
- Chemical Exposure: Evaluate resistance to oils, solvents, or corrosive atmospheres; polyimide films offer chemical stability but check adhesives for compatibility.
Control And Safety
- Temperature Control: Film heaters require external thermostats or controllers for closed-loop control. Plan for appropriate sensors and controllers.
- Overcurrent Protection: Provide fusing, breakers, or temperature cutouts when using mica-insulated wires with high-power elements.
Installation And Serviceability
- Flexibility: Thin mica wires and film heaters are flexible but vary in bend radius. Check manufacturer guidelines for bending and stripping to avoid damaging insulation.
- Replacement And Sizing: For replacement heating strips, confirm physical dimensions and mounting method. Multi-pack film heaters are useful for repeat replacements.
Cost-Benefit And Application Fit
- High-Temperature Durability: Mica-insulated wires excel where sustained high temperatures and flame resistance are essential.
- Surface Heating Efficiency: Polyimide film heaters provide fast, localized heating with minimal thermal mass when controlled properly.
- Modular vs Custom: Off-the-shelf film heater sizes suit many applications; custom mica strip heaters or fabricated assemblies may be necessary for nonstandard shapes.
Comparison Perspectives
- Industrial Ovens/Kilns: Prefer mica-insulated wiring and dedicated mica strip heater assemblies that tolerate 400–500°C sustained conditions.
- Appliance Repair: Mica-insulated wires often match original equipment wiring and provide fire-resistant replacements for elements and connectors.
- Electronics And Instrumentation: Use low-voltage PI film heaters when surface temperature limits and low mass are advantages; pair with precise controllers.
When selecting a mica strip heater or mica-insulated cable, verify the full specification sheet for insulation construction, rated temperatures, dielectric strength, and installation instructions. Cross-check compatibility with controllers, sensors, and mounting substrates for safe, reliable operation.
