0.35mm² High Temperature PTFE Wire: Superior Performance in Extreme Environments

Engineered for reliability where ordinary wires fail, our 0.35mm² High Temperature PTFE Wire is the ultimate solution for demanding applications across aerospace, automotive, and industrial sectors. This fluorinated wire delivers exceptional thermal stability, mechanical durability, and electrical integrity in temperatures up to 250℃. Built with premium Polytetrafluoroethylene (PTFE) insulation, it ensures consistent performance in high-heat, high-stress environments where precision and safety are non-negotiable.

Key Features & Technical Specifications

✔ Exceptional Temperature Resistance: Operating range from -60°C to +250℃, with short-term tolerance up to 350℃ . Perfect for extreme thermal cycling applications.
✔ Premium PTFE Insulation: Offers superior dielectric strength, low dissipation factor, and resistance to moisture, chemicals, and UV exposure .
✔ Optimized Conductor Design: 0.35mm² (22 AWG) conductor available in tinned copper, silver-plated copper, or bare copper stranding (e.g., 19/0.15mm) for excellent flexibility and current carrying capacity .
✔ High Voltage Rating: Rated up to 600V, making it suitable for both low-voltage instrumentation and high-voltage power circuits .
✔ Flame Resistance & Safety: Complies with UL VW-1 flame test standards; features low smoke generation and zero halogen composition for enhanced safety

Q&A

Q1: What makes PTFE wire suitable for high-temperature applications?
A: PTFE (Polytetrafluoroethylene) maintains excellent dielectric properties and mechanical flexibility at extreme temperatures (-60°C to +250°C), unlike PVC or PE which would degrade. Its molecular structure provides exceptional thermal stability.

Q2: Can this wire be used in automotive engine compartments?
A: Yes, specifically for sensor wiring near exhaust systems, turbochargers, and in hybrid vehicle power systems where temperatures regularly exceed 150°C.

Q3: What conductor options are available for the 0.35mm² PTFE wire?
A: We offer multiple options:

• Tinned copper (standard, best for general high-temp use)

• Silver-plated copper (superior for high-frequency applications)

• Nickel-plated copper (optimal for extreme corrosion environments)

Q4: Is this wire compliant with international safety standards?
A: Yes, our PTFE wire meets UL 10393, MIL-W-16878/4, and RoHS requirements. We can also customize to meet specific customer certification needs.

Q5: What customization options do you offer for bulk orders?
A: We provide comprehensive customization:

• Custom colors and printing (including UL-style legends)

• Special packaging (100m/500m reels, ESD-safe)

• Modified OD tolerances (±0.2mm standard, ±0.1mm precision)

• Composite constructions (twisted pairs, shielded versions)

• Special testing (hi-pot, continuity, 100% quality inspection)
