Power Enabler — Winding Wire
More Compact Motors. Better Thermal Performance. Extreme Environments.
Gore-insulated magnet wire enables tighter winding densities and superior thermal performance in motors, transformers, and solenoids that operate in environments where conventional enamel-insulated wire fails. ePTFE insulation's combination of thin wall, high dielectric strength, and chemical inertness unlocks new design possibilities for demanding industrial and aerospace electromagnetic components.
Gore-insulated magnet wire delivering superior thermal performance and compactness for motors, transformers, and solenoids operating in extreme environments.
Why Choose Gore Magnet Wire?
Thinner Insulation Wall, Higher Slot Fill
Gore ePTFE insulation achieves the required dielectric strength at a thinner wall than conventional polyimide or enamel insulation. This allows more copper to fit in the motor slot, directly improving motor efficiency, torque density, and power output without increasing frame size.
Rated for Extreme Operating Temperatures
ePTFE maintains its insulation integrity from −65°C to +200°C continuously, making Gore magnet wire suitable for traction motors, aerospace actuators, and oil and gas submersible pumps where thermal limits are routinely approached.
Chemical and Fluid Resistance
Unlike enamel-insulated wire, Gore magnet wire is unaffected by exposure to hydraulic fluids, lubricating oils, fuels, and industrial solvents. This eliminates insulation degradation in motors operating in chemically aggressive environments.

Frequently Asked Questions
How does Gore magnet wire compare to polyimide-insulated (e.g., Kapton) magnet wire?
Gore ePTFE insulation matches or exceeds polyimide in dielectric strength while offering superior chemical resistance and a lower dielectric constant. ePTFE is also inherently non-absorbing of moisture, which is a limitation of polyimide in humid environments.
Can Gore magnet wire be wound on standard winding equipment?
ePTFE-insulated wire requires attention to tension control during winding as ePTFE is softer than enamel insulation. Contact RSTECH Electronics to discuss winding recommendations and available technical support from Gore.
Is this wire suitable for use in vacuum impregnation (VPI) processes?
Gore magnet wire is compatible with vacuum pressure impregnation processes commonly used in motor manufacturing. ePTFE's chemical inertness ensures compatibility with common VPI resins.
What is the maximum continuous operating temperature?
Gore ePTFE-insulated magnet wire is rated for continuous operation at up to +200°C. Short-term excursions above this temperature are application-dependent — contact RSTECH Electronics for guidance.
