High Temperature Non Woven Filtration Fabric P84 For Municipal Solid Waste Incineration Power Plant
High Temperature Non Woven Filtration Fabric P84 For Municipal Solid Waste Incineration Power Plant
Farrtex® P84 high-temperature filter bags are engineered for harsh industrial environments, utilizing advanced P84 fibers combined with PTFE scrim technology. Designed for high-temperature, corrosion-resistant, and long-lasting filtration, these bags excel in applications such as coal-fired boilers, waste incineration, cement kilns, and chemical processing. They ensure efficient particulate capture and help industries meet the world’s most stringent environmental emission standards.
Core Advantages
1. Exceptional Temperature Resistance
-
Continuous Operating Temperature: ≤260°C (500°F), with instantaneous tolerance up to 280°C (536°F).
-
Thermal Stability: Synergy between P84 fibers and PTFE scrim minimizes thermal shrinkage (MD: <15%, XD: <10%).
2. Superior Chemical Resistance
-
Anti-Corrosion Design: P84 fibers inherently resist acids, alkalis, and oxidation, while PTFE scrim provides additional protection against corrosive gases like sulfides and chlorides.
3. High Mechanical Strength & Durability
-
Peak Load Resistance: MD >900 N/5cm, XD >1200 N/5cm, ideal for high-pressure pulse-jet cleaning systems.
-
Abrasion Resistance: PTFE dipping and single-side calendering create a smooth surface to reduce dust adhesion, extending service life by over 30%.
4. Intelligent Filtration Efficiency
-
Balanced Air Permeability: 180-240 L/dm²/min (200Pa), achieving low resistance and high precision (captures sub-micron particles).
-
Precision Weight & Thickness: 550±5% g/m² with 2.4±0.2 mm thickness ensures stable filtration layer integrity.

Frequently Asked Questions (FAQ)
Q: How does P84 compare to fiberglass filter bags?
A: P84 offers better temperature resistance, anti-hydrolysis properties, and 50% longer lifespan, especially suited for high-humidity gases.
Q: Are anti-static treatments available?
A: Optional carbon fiber blends (surface resistance ≤10⁹Ω) eliminate explosion risks for flammable dust (e.g., coal, aluminum powder).
Q: How to identify bag failure?
A: Monitor sudden pressure drops or abnormal emissions. Professional leak testing every 6 months is recommended.
Q: What is the minimum order quantity (MOQ)?
A: Standard products: MOQ 50 bags; Custom designs: MOQ 100 bags. Trial orders are accepted.
