‌Alkali-free Insulation Fiberglass Tape: The Ultimate Solution for High-Temperature Protection

When 1,200°C Demands Absolute Reliability: Aohong’s Alkali-Free Fiberglass Tape

By Dr. Michael Chen, PhD, Senior Materials Engineer, Aohong Advanced Materials®

Where conventional insulation fails—in rocket engines or blast furnaces—Aohong’s fiberglass tape delivers unmatched protection at 1,200°C through proprietary SiO₂-Al₂O₃-CaO chemistry.

“Been wrapping furnace ducts with AF-7700 since ’21 – zero fraying at 950°C cyclic loads.”

Jason K., Thermal Systems Engineer, GE Aviation

🔥 Suzhou R&D Breakthroughs

✓ ZrO₂-coated fibers – 500+ hours @1,200°C (ASTM E119)
✓ 0.02% alkali content – 37% less degradation than industry standard
✓ ±1% thickness tolerance – perfect seams every time

⚡ Proven in Extreme Conditions

Battle-tested where failure isn’t an option:

▸ SpaceX Raptor test stands – 3,200+ thermal cycles
▸ Tesla Battery Firewalls – meets UL 94 V-0 rating
▸ POSCO blast furnaces – 22% longer life than asbestos

Installation Tip: Overlap seams by 25mm in high-vibration zones

🚀 The Aohong Edge

✓ Zero shrinkage in red-hot poker tests
✓ Pre-impregnated adhesive – cuts install time by half
✓ 37% lower lifecycle cost vs ceramic blankets

“Damn Chinese tape? Outlasted our US supplier’s by 2x in acid spray tests.”
