PPS Pleated Felt Filter Media for High-Temperature Cartridge Filters

Engineered PPS pleated needle felt media for high-temperature cartridge filtration, delivering stable pleat geometry and long-term reliability.

PPS pleated felt filter media is engineered for high-temperature cartridge dust collection systems operating under continuous thermal and chemical stress.
Manufactured from high-quality polyphenylene sulfide (PPS) needle felt, this media is designed to provide stable pleating performance, consistent filtration efficiency, and long service life in demanding industrial environments.

Through a specialized high-temperature stiffening and setting process, the PPS needle felt achieves enhanced rigidity and dimensional stability. This treatment enables the material to maintain stable pleat geometry during pleating, installation, and long-term operation, making it suitable for pleated filter cartridge manufacturing.

This PPS pleated filter media has been in continuous industrial use in China for more than ten years, with applications covering cement plants, steel mills, coal-fired boilers, and waste incineration facilities.
Over long-term operation, the material has been validated by the market under severe working conditions, demonstrating stable structural performance, reliable filtration behavior, and consistent quality in large-scale dust collection systems.

Optional surface treatments such as PTFE membrane lamination, carbon impregnation (antistatic), and high-temperature stiffening are available to further enhance filtration performance, cleanability, and pleat durability for long-term operation.

Key Advantages of PPS Pleated Felt Filter Media

✔ High-Temperature Resistance
Designed for continuous operation up to 170 °C, with short-term temperature peaks up to 190 °C, meeting the thermal requirements of most high-temperature cartridge filter systems.

✔ Excellent Chemical Resistance
PPS fiber chemistry provides strong resistance to acidic gases and chemically aggressive flue-gas components commonly found in industrial processes.

✔ Stable Pleat Geometry
The high-temperature stiffening and setting process improves media rigidity and dimensional stability, ensuring consistent pleat structure under thermal cycling and pulse-jet cleaning.

✔ High Filtration Efficiency
Low air permeability combined with fine fiber structure enables effective capture of fine and submicron particles, particularly when combined with PTFE membrane finishing.

✔ Proven Long-Term Industrial Performance
More than a decade of field application in China confirms reliable operation, structural stability, and suitability for continuous industrial dust collection.

Field-Proven Performance / Market Validation

This PPS pleated needle felt filter media has been in continuous industrial use in China for more than ten years, serving a wide range of high-temperature dust collection systems.

During long-term operation across cement plants, steel mills, coal-fired boilers, and waste incineration facilities, the media has been exposed to elevated temperatures, chemically aggressive flue gas, and repeated pulse-jet cleaning cycles.

Over this extended period of field application, the material has demonstrated:

• Stable pleat geometry under sustained thermal cycling

• Consistent filtration behavior in high-dust-load environments

• Reliable mechanical integrity during long-term cartridge operation

• Repeatable quality performance across large-scale installations

This decade-long market validation confirms that the PPS pleated felt media is not a laboratory-developed or short-term solution, but a mature, field-proven filtration material suitable for continuous industrial operation under severe working conditions.

Technical Notes

① Air permeability measured at ΔP = 200 Pa.
② Filtration precision refers to the minimum particle size effectively captured before dust cake formation; actual filtration efficiency improves as a stable dust layer forms during operation.
③ MERV grade tested according to ASHRAE 52.2 (USA) or EN 779 (Europe).
