designed for demanding industrial filtration applications.
Combining advanced P84 fibers with PTFE scrim, this
high-performance filter bag excels in extreme environments,
offering superior durability, thermal stability, and chemical
resistance. Below, we detail its key features, advantages,
technical parameters, and answers to common questions.
Key Features of P84 Filter Material
- Premium Material Composition
- P84 Fiber: A high-temperature polyimide fiber known for exceptional heat
resistance (up to 260°C continuous) and resistance to chemical
corrosion.
- PTFE Scrim: A polytetrafluoroethylene base fabric that enhances dimensional
stability, reduces shrinkage, and improves mechanical strength.
- Optimized Physical Properties
- Weight: 550±5% g/m² ensures robust filtration efficiency without
compromising airflow.
- Thickness: 2.4±0.2 mm provides a balance between particle retention and
permeability.
- Air Permeability: 180-240 L/dm²/min (at 200Pa) allows efficient gas flow while
capturing fine particulates.
- Advanced Mechanical Processing
- Heat Setting & Calendering: Ensures uniform fiber alignment and surface smoothness.
- PTFE Dipping: Adds a protective layer to enhance abrasion resistance and
prolong service life.
- Exceptional Mechanical Performance
- Peak Load Resistance: MD >900 N/5cm; XD >1200 N/5cm (ideal for high-pressure
systems).
- Low Strain & Shrinkage: MD strain <35%, XD strain <50%; linear shrinkage <15%
(MD) and <10% (XD).
- Temperature Resistance
- Continuous Use: ≤260°C (e.g., coal-fired boilers, cement plants).
- Instantaneous Tolerance: ≤280°C (short-term exposure during peak operations).
Why Choose Farrtex® P84 Filter Material?
- Longer Lifespan: PTFE scrim minimizes shrinkage and deformation, reducing
replacement frequency.
- Energy Efficiency: Optimal air permeability lowers pressure drop, saving operational
costs.
- Chemical Resilience: Resists acids, alkalis, and solvents, making it suitable for
harsh industrial emissions.
- Regulatory Compliance: Meets stringent environmental standards for particulate emission
control.
