Product Introduction:
Haoyang Environmental's advanced safety solution combines aluminum trihydrate (ATH)-enhanced bentonite with fire-resistant geotextiles, achieving ASTM E84 Class A flame spread rating (FSI≤25, smoke density≤450) while maintaining ≤10⁻¹¹ m/s water permeability. The 8mm thick composite withstands 2-hour fire resistance tests (EN 1366-4) without structural failure, with the ATH filler releasing bound water at 200°C to actively suppress combustion. Third-party verified to maintain 90% of its waterproofing capacity after thermal cycling (50 cycles of 200°C heating/cooling), this system provides critical protection for subway tunnels and underground utilities where both fire safety and waterproofing are paramount.
Our high-performance blanket features a 4.8kg/m² sodium bentonite core mechanically bonded between two 300g/m² polypropylene geotextiles through precision needle-punching (220 punches/cm²). This construction delivers 18kN/m tensile strength (ASTM D4595) while allowing 12% elongation before bentonite layer disruption, accommodating structural movements in dynamic environments. The pre-activated formulation achieves ≤10⁻¹² m/s permeability within 8 hours of hydration (vs. 24-48 hours for conventional GCLs), with field data showing 100% self-sealing of 15mm cracks in concrete substrates.
