Product Description

High Performance PPS Needle Felt

Technical Overview

Polyphenylene Sulfide (PPS) needle felt is a high-performance, non-woven filtration fabric manufactured through a precise needling process. Engineered for demanding high-temperature filtration applications where chemical resistance and thermal stability are paramount.

Key Characteristics

Excellent Thermal Stability: Maintains dimensional stability and mechanical integrity in continuous operating temperatures up to 190°C (374°F), with short-term exposure resistance up to 232°C (450°F)
Outstanding Chemical Resistance: Remarkable resistance to acids, alkalis, and organic solvents, making it suitable for filtering chemically aggressive flue gases. Inherently hydrolytic stable
Flame Retardancy: Inherently flame-resistant, meeting various industry standards for fire safety
Filtration Performance: Dense, porous structure with high filtration efficiency for fine particulate matter, achieving low emissions. Surface treatments can further enhance dust release and efficiency

Primary Applications

PPS needle felt is the filter media of choice for baghouses and cartridge filters in the following industries:

Coal-Fired Boilers / Power Plants: Filtering fly ash from flue gas
Waste Incineration: Filtering gases from municipal or industrial waste incineration
Cement Production: Used in kiln, raw mill, and clinker cooler baghouses
Pulp & Paper Industry: Recovery boiler applications
Chemical Process Industries: Filtration in processes involving acidic or corrosive environments

Important Operational Limitation

PPS is not suitable for environments with high oxygen (>15%) content at elevated temperatures (above 140°C/284°F), as it can undergo oxidative degradation. Its performance against certain strong oxidizing agents is also limited.

Technical Parameters

Parameter	Typical Range
Weight	500 - 600 g/m²
Thickness	1.8 - 2.5 mm
Tensile Strength (Warp/Weft)	>800 / >1200 N/5cm
Operating Temperature	Continuous: 150-190°C; Peak: 232°C
Fineness	Commonly 2.0 - 3.0 denier fibers
Surface Treatments	Optional singeing, calendering, PTFE lamination, or membrane coating

Conclusion

PPS needle felt represents a robust and reliable solution for high-temperature, corrosive gas filtration. Its unique combination of thermal resilience, chemical inertness, and fine filtration capability ensures long bag life, low maintenance costs, and high collection efficiency in challenging industrial settings. Proper selection requires careful consideration of the specific gas composition, temperature profile, and particulate characteristics of the application.
