Product Description
Volcanic rock-derived continuous fibers deliver unmatched thermal resistance (-260°C to 880°C) and tensile strength up to 4,840MPa (1.4x E-glass). Certified to ASTM/GB standards, these eco-friendly fibers enable lightweight solutions in aerospace, construction, and filtration industries.
Core Advantages
- • Extreme Thermal Stability: 1,000°C short-term exposure (fireproof suits & spacecraft shielding)
- • Superior Corrosion Resistance: Alkali retention ≥85% (outperforms glass fiber in concrete reinforcement)
- • Eco-Efficiency: Carbon-neutral production, 16x lower energy vs carbon fiber
