Kevlar high-temperature air slidea fabric is a specialty industrial textile manufactured using DuPont’s Kevlar aramid fibers, specifically engineered for extreme high-temperature and high-pressure operating conditions. While maintaining excellent air permeability, this product offers significantly superior heat resistance and mechanical strength compared to conventional materials.
Основные характеристики
Ultra-high temperature resistance:
- Continuous service temperature range: -196°C to 260°C
- Short-term exposure resistance up to 480°C
Outstanding mechanical properties:
- Tensile strength >3000MPa
- Wear resistance meets highest grade of ISO 12947-3 standard
Special functions:
- Inherent flame retardant (LOI >28)
- Optional anti-static treatment (surface resistance 10⁶-10⁹Ω)
- Resistant to most acids and alkalis (except concentrated sulfuric acid and strong oxidizers)
