Key Advantages 

1. Space-Saving Profile:Reduced outer diameter enables higher-density wiring in compact control panels, avionics racks, and miniaturized electronics.

2. Enhanced Flexibility:Exceptional bendability allows easy navigation through tight corners and confined spaces without stress on insulation or conductor.

3. Mili tary-Grade PTFE Insulation:Despite reduced dimensions, retains full PTFE advantages: flame retardance, chemical resistance, weather stability, and -60°C to 250°C operation.

4. Optimized for 250V Systems:Matched precisely to low-voltage applications—eliminates bulk and weight of higher-rated insulation while maintaining full dielectric integrity.

Application
  • Aerospace & Defense: Internal wiring of aircraft, missiles, and mili tary electronics.
  • High-Temperature Instrumentation: Sensors and control systems in industrial furnaces and engine compartments.
  • Rugged Electronics: Portable test equipment and devices exposed to extreme vibration and thermal stress.
  • Space-Constrained Environments: Compact electronic devices where flexibility and weight savings are essential.
Why Choose Our AF250 Series PTFE Insulated Wire?

The AF250-2Q 250°C high temp wire is the preferred choice for applications requiring proven PTFE reliability with cost-effective extruded construction. As a professional PTFE insulated wire, its silver plated copper wire conductor ensures low resistance and direct solderability, while the thin wall insulation wire structure provides uniform dielectric protection at 250V AC across a -60°C to 250°C temperature range.This versatile product performs equally well as aerospace PTFE wire, industrial hookup wire, industrial heat resistant cable, and auto wire with PTFE insulation. With exceptional chemical, oil, and weather resistance plus self-extinguishing flame retardance, it delivers mission-ready performance for general-purpose aviation and industrial wiring.
