Product Description
PPS Needle Punched Felt is a high-temperature filtration material made from polyphenylene sulfide (PPS) fibers through a three-dimensional needle-punching process. It is designed for demanding dust collection applications where ordinary filter media may not provide enough temperature resistance or chemical stability.
With a practical balance of heat resistance, chemical stability, mechanical strength, and filtration performance, PPS felt is particularly suitable for industrial gas filtration in power generation, waste incineration, coal-fired boilers, and other challenging operating environments.
Key Benefits
- High-temperature performance: suitable for long-term operation at around 190°C
- Good chemical stability: designed for demanding industrial gas environments
- Strong fiber structure: helps maintain mechanical performance during filtration
- Suitable for acidic flue gas: particularly useful where sulfur-containing gases are present
- Three-dimensional needle-punched construction: provides a durable nonwoven filtration structure
- Industrial-duty filtration: suitable for continuous dust collection applications
- Available for filter bag production: can be processed into filtration products for industrial dust collectors
