Outstanding chemical stability: Resistant to corrosion by strong acids and alkalis (superior to SiO₂/Al₂O₃ fibers), oxidation-resistant, non-volatile, and pollution-free; controllable insulation-to-conductivity characteristics at high temperatures.
Versatile form adaptability: Can be processed into felts, fabrics, papers, boards, and more; suitable for furnace linings, gaskets, composite reinforcements (enhancing fracture toughness), battery separators, aerospace thermal insulation layers, etc.
Ultra-high temperature resistance: Melting point reaches 2,590–2,700°C; suitable for long-term use at ≥1,500°C, while maintaining fiber integrity during short-term exposure up to 2,200°C (operational temperature range: approx. -269°C to 2,000°C).
Excellent thermal insulation and thermal shock resistance: Features extremely low thermal conductivity (0.08–0.12 W/m·K), low heat capacity, and minimal heat storage; a low coefficient of thermal expansion provides strong thermal shock resistance, making it ideal for environments with frequent temperature fluctuations.
