AFK250-2Q PFA Extruded Hookup Wire 250V Lightweight Heating Building Installation Wire
Product Description
The AFK250-2Q is a high-performance aerospace-grade hook-up wire with a silver-plated copper conductor (excellent conductivity, flux-free direct soldering) and PFA insulation (a melt-processible fluoropolymer).Via PFA melt extrusion, it is more cost-effective than the traditional PTFE cold-extruded AF250 series while maintaining high performance. Rated at 250V AC, it works reliably in extreme environments (-60°C to +200°C), with excellent resistance to temperature, oil, abrasion, chemicals and aging, as well as self-extinguishing flame retardancy, ideal for harsh-environment instrument and equipment connections.

Key Advantages 
  1. Superior Conductivity & Solderability: The silver-plated copper conductor ensures excellent electrical conductivity and enables easy, flux-free soldering for reliable terminations.
  2. PFA Extruded Insulation: Uniform, dense insulation layer for stable electrical performance, standard for high-quality 250°C high temp wire.
  3. Thin Wall Construction:Balanced protection and flexibility for general-purpose applications, ideal for use as industrial hookup wire.
  4. Wide Temperature Range: Reliable from -60°C to +200°C continuous; short-term to 250°C, cementing its status as a durable industrial heat resistant cable.
  5. Superior Chemical Resistance: PFA insulation exhibits outstanding resistance to corrosion, with only a few substances like molten alkali metals, fluorine, and strong oxidizing agents causing reactions.

  6. Excellent Weather Resistance: PFA is non-hygroscopic, non-flammable, and highly stable against oxygen and UV radiation, ensuring long-term reliability in outdoor applications.

  7. Abrasion & Oil Resistance: The robust PFA insulation provides good mechanical protection against wear, oils, and industrial fluids.

Application
  • Aerospace and aviation wiring – The PFA insulation provides flame retardance and broad temperature tolerance from -60°C to 200°C, while resisting fuels and hydraulic fluids.

  • Internal wiring of electrical appliances – The silver-plated copper conductor enables flux-free soldering for reliable connections in confined spaces.

  • High-temperature environments – PFA's thermal stability maintains electrical integrity during prolonged exposure up to 200°C without embrittlement.

  • Chemical processing equipment – The chemically inert PFA insulation withstands aggressive acids, solvents, and oxidizers without degradation.

  • High‑reliability systems – Silver-plated conductor ensures consistent conductivity, while PFA resists UV, moisture, and aging for decades of service.

Why Choose Our AFK250 Series PFA Insulated Wire?
The AFK250-2Q hook-up wire delivers uncompromising performance in the most demanding environments. Its PFA insulation combines PTFE-grade chemical resistance with exceptional thermal stability from -60°C to +200°C, while the silver-plated copper conductor enables flux-free soldering for reliable connections. This cost-effective alternative to PTFE cold-extruded products is flame-retardant, chemically inert, and proven reliable in aerospace, industrial, and mission-critical applications worldwide—fully compliant with GJB 1640 standards.
