Key Performance Advantages

1. Cost-Effective Thermal Solution
   • PVC insulation reduces 40% cost vs. silicone/FEP, ideal for budget-sensitive industrial heating systems .
2. Multi-Alloy Flexibility
   • Nicr35/20: 1,200°C max conductor temp (furnace coils) .
   • Inconel 625: Superior chloride resistance for marine/chemical environments .
3. Easy Installation & Customization
   • PVC’s rigidity simplifies routing in control panels; supports custom gauges (0.2–10mm) and colors (6+ RAL) .

Alloy Selection Guide

Alloy Max Temp Key Strength Ideal Application

Nicr35/20 1,200°C Oxidation resistance Industrial heaters, kilns

Nicr AA 1,150°C High aluminum content (anti-sag) Oven heating elements

Inconel 600 1,000°C Acid/caustic resistance Chemical processing equipment

Inconel 625 1,000°C Chloride/pitting resistance Offshore platforms, marine

Application Scenarios

"Optimized for moderate-heat industrial systems:

• HVAC Duct Heating – PVC insulation resists moisture in ventilation systems (<90°C).
• Food Processing Lines – Inconel 625 conductors withstand steam cleaning (FDA-compliant).
• Plastic Extruders – Nicr35/20 coils provide stable heat for polymer molding.
• Low-Cost Thermal Prototypes – PVC’s affordability enables rapid OEM testing

Critical Limitations & Compliance

• Temperature Caution:"PVC insulation degrades above 105°C – not suitable for high-temp zones (e.g., engine bays). For >105°C, upgrade to FEP/PFA insulation ."
• Regulatory Notes:
  • Complies with RoHS/REACH (heavy-metal-free).
  • UL 758 certified for appliance wiring (US/CA markets) .

Customization Options

• Conductor Gauges: 0.2mm–10mm (e.g., 1.5mm Nicr35/20: 0.617 Ω/m) .
• Colors: White, black, red, yellow, blue, green (circuit ID).
• Packaging: Moisture-proof spools + wooden crates (export-ready).
• Certification: ISO 9001 + test reports on request .

Remarks: The size can be changed if special requirement.
The thickness of insulation also can be adjusted by special requirement. We can do insulation thickness 0.2mm to 2.5mm


Available conductor alloy grade as follows:

Available color: Black, white, green, red, yellow, blue
