Industrial-Grade Mica Tape Impregnated High-Temp Wire, -Certified (-80°C to 500°C)

Premium Construction & Compliance

• Conductor: Silver-plated/Nickel-coated copper strands (e.g., 19/0.26mm) – enhanced oxidation resistance at extreme temperatures
• Insulation: Impregnated phlogopite mica tape + fiberglass backing:
  • Fire Resistance: Withstands 900°C for 3 hours (per IEC 331/BS 6387 CWZ) with zero flame propagation
  • Chemical Immunity: Resists acids, oils, solvents, and radiation up to 10^(9) Rad (excludes sulfuric acid)
• Certifications: Complies with UL 5128/UL 5335 (AWM), RoHS, REACH, IEC 60335-1 (household safety)

Competitive Advantages

• Unmatched Fire Survival:
  • Self-extinguishing (VW-1/UL 94), zero toxic fumes – critical for mass transit/aircraft wiring
  • Maintains dielectric integrity at 1000°C (50% dielectric strength retention at 700°C)
• Longevity & Reliability:
  • >10,000 hours service life at 500°C (vs. silicone’s 5,000 hours)
  • Halogen-free (IEC 60754-1), safe for enclosed spaces
• Eco-Safety:
  • Non-toxic, odorless silicone binder – complies with FDA 21 CFR for household appliances

Target Applications

• Industrial Heating: Furnace sensors, glass plants (≤1000°C environments)
• Critical Infrastructure: Nuclear reactors (radiation-resistant)
• Household Appliances: Ovens, dryers (IEC 60335-1 compliant ≤500V AC)
• Transportation: Shipboard cables, aircraft engine wiring (FAR 25.853 fireproof)

Customization Options

• Shielding: SS304 braid or aluminum foil for EMI-heavy environments (e.g., VFD motors).
• Insulation Layers: 1–3 mica tape wraps with 20–50% overlap (customizable)
• Packaging: 30m rolls (standard) or custom lengths up to 1000m.
• Certifications: ATEX/IECEx reports for Zone 1 hazardous areas.
