Aramid air slide fabric is a high-performance material used in pneumatic conveying systems, fluidized beds, and dust filtration applications. Made from aramid fibers (e.g., Nomex, Kevlar), it offers exceptional heat resistance, mechanical strength, and chemical stability, making it ideal for harsh industrial environments.
1. Key Features
✔ Extreme Temperature Resistance
Continuous use: -50°C to +220°C
Short-term exposure: Up to 300°C (flame-retardant)
✔ High Strength & Durability
Excellent abrasion resistance for long service life
Low elongation under tension
✔ Chemical Resistance
Resistant to acids, alkalis, and organic solvents
✔ Controlled Air Permeability
Uniform pore structure (10–100 μm) for stable airflow
2. Applications
High-Temperature Pneumatic Conveying (e.g., carbon black, metal powders)
Fluidized Bed Dryers & Reactors
Hot Gas Filtration (e.g., cement kilns, centrales eléctricas)
Explosive/Flammable Dust Collection (anti-static options available)
3. Comparison with Standard Synthetic Fabrics
Propiedad | Aramid Fabric | Standard Polyester Fabric |
Temperatura máxima | 220°C+ | 120°C |
Abrasion Resistance | ★★★★★ | ★★★☆☆ |
Chemical Resistance | ★★★★★ | ★★★☆☆ |
Coste | Higher | Lower |
4. Selection Guide
For extreme heat/corrosion: Pure aramid + PTFE coating
For cost-sensitive harsh environments: Aramid blend fabrics
Anti-static requirements: Conductive fiber interwoven versions
5. Maintenance Tips
- Clean with low-pressure air pulses (<0.3MPa)
- Avoid mechanical scraping on active surfaces
- Inspect quarterly for fiber degradation in acidic/alkaline service
This specialty material delivers unmatched performance where conventional synthetics fail, particularly in thermal and chemical stress conditions.
