Mica Tape Wire

Mica tape AWM wire uses wrapped mica tape as the primary insulation material — a mineral-based insulation that provides temperature ratings of 200°C to 450°C. Mica is a crystalline silicate mineral that retains its electrically insulating form at temperatures that exceed the practical range of many polymer-insulated AWM wires, making mica tape wire a common selection for internal wiring near the high-temperature zones of industrial thermal equipment, and for equipment leads operating continuously above 200°C.

CableApex supplies mica tape AWM wire as a UL Recognized Component — file on record — covering seven styles. Voltage, temperature, conductor size, and construction depend on the selected UL style; several styles carry dual 200°C / 450°C ratings. RoHS and REACH documentation is available on request.

UL Style	Voltage	Temperature	Primary application
UL 5107	600V AC	200 / 450°C	High-temperature equipment internal wiring; widest AWG range; single or multi-conductor
UL 5128	300V AC	450°C	300V internal wiring near high-temperature zones; optional SS304 shield
UL 5334	300V AC	450°C	Compact internal wiring where a smaller overall diameter is needed
UL 5335	600V AC	450°C	600V internal wiring leads in high-temperature equipment
UL 5359	600V AC	200 / 450°C	Thin-wall construction; single or multi-conductor instrumentation leads
UL 5360	300V AC	200 / 450°C	300V single-conductor internal wiring in compact high-temperature equipment
UL 5476	600V AC	450°C	600V internal leads in high-temperature equipment; optional binder layer

The mica styles share mica tape insulation but differ in voltage rating, temperature class, insulation wall, AWG range, and optional shielding or assembly. UL 5107 offers the widest AWG range; UL 5334 and UL 5359 provide more compact constructions; UL 5128, 5334, and 5360 cover 300V circuits; and 5107, 5335, 5359, and 5476 cover 600V. Selecting the correct style matches the wire to the application’s voltage, temperature, and conductor requirements.

To request a quotation, send the UL style number, conductor size, voltage, temperature, construction (single or multi-conductor, shield, covering), quantity, and a brief description of the application. Quotations are returned within 24 hours, and mixed-style or mixed-AWG orders are accepted on a single shipment.
