Polyphenylene Sulfide (PPS) Monofilament

Engineered for heat, chemical and abrasion resistance — our PPS monofilaments are a premium solution when ordinary polymers fail. Used widely in filtration media, high-temperature meshes and demanding paper-making applications, PPS offers exceptional stability across the most aggressive process conditions.

Note: exact performance depends on grade, post-treatment and weaving/processing conditions. Provide operating temperature, chemical exposure and machine parameters for precise recommendations.

Why Choose Our PPS Monofilaments?

• High continuous service temperature. PPS maintains mechanical strength at elevated temperatures and is suitable for continuous use well above 150°C in many grades. 

• Outstanding chemical resistance. Resistant to acids, alkalis, solvents and most industrial gases — ideal for flue-gas filtration and corrosive process streams. 

• Dimensional and thermal stability. Low shrinkage and predictable behaviour under thermal cycling keep woven meshes and fabrics stable on high-speed machines. 

• Long service life in harsh environments. PPS is frequently selected over other polymers where longevity and lower lifecycle cost are priorities. 

• Custom options & quality control. Multiple diameters, colours and surface finishes, produced under strict QC with traceable batch records for repeatable performance.

Typical Applications

 

• High-temperature filtration: bag filters, cartridge and woven filter cloths for power plants, cement kilns and incinerators. 

• Paper industry components: dryer fabrics, forming meshes and special filter media where temperature and chemical exposure exceed PET/PA limits. 

• Industrial meshes & screens: support media for membrane systems, heat-resistant conveyor belts and separation screens.

• Specialty technical textiles: braided sleeving, composite reinforcements and flame-retardant webbing.

 

Performance Benefits

 

• Higher uptime: longer wear life reduces changeovers and maintenance stops.

• Stable on-machine behaviour: lower shrinkage and predictable thermal response cut trial time.

• Lower lifecycle cost: fewer replacements and less consumable spend over time.

• Safer operation: inherent flame resistance and low moisture uptake improve process reliability.

Quality & Manufacturing Highlights

• Manufactured with controlled extrusion and diameter monitoring to minimise filament variation. 

• Sourced and processed to meet demanding industrial filtration and textile standards.

• Available with post-treatments (heat-setting, antistatic finishes) to tailor behaviour for specific end uses.

How to Select the Right PPS Monofilament

1. Tell us your process conditions: continuous/temp peaks, chemical exposures, abrasive load and machine speed.

2. Choose filament diameter and finish based on required permeability, open area and mechanical loading.

3. Pilot & test: we can supply sample coils or small-run woven/knitted panels for on-machine evaluation.

4. Scale production: once validated, we deliver full production runs with batch traceability and export-grade packing.

FAQs

Q — Can PPS replace polyester (PET) or nylon in my application?
A — In many high-temperature or chemically aggressive environments, PPS outperforms PET/PA. However, a direct replacement should be tested — we recommend trials to confirm permeability, abrasion and shrinkage under your conditions.

Q — What are the shipping lead times for samples and production?
A — Samples: typically within 7–14 days (subject to stock and diameter). Production: generally 15–30 days depending on order size and custom specifications.

Q — Do you offer technical support for weaving and mesh production?
A — Yes. We advise on weave patterns, opening size and post-treatments to achieve the required filtration/structural performance.

Application Case — High-Temperature Dryer Section in a Paper Mill

One of our long-term partners, a kraft paper manufacturer in Eastern Europe, faced repeated downtime and high replacement costs in the dryer section of their paper machine. Their previous dryer fabrics, made from conventional polyester monofilaments, suffered from hydrolysis, shrinkage, and strength loss after prolonged exposure to high temperature and humidity.

Challenges

• Dryer section temperature exceeded 180 °C, causing polyester fabrics to deform.

• Frequent fabric changes every 5–6 months, disrupting production.

• Uneven paper surface and reduced drying efficiency due to unstable air permeability.

Our Solution

Yarns Technology supplied a custom-engineered dryer fabric woven from polyphenylene sulfide (PPS) monofilaments with a controlled yarn diameter and optimized air permeability of 500 CFM.
The PPS material offered:

• Superior heat and hydrolysis resistance for stable performance above 190 °C.

• Low thermal shrinkage ensuring consistent tension and smooth paper surfaces.

• Excellent chemical resistance against paper-making additives and cleaning agents.

Results

• Service life extended from 6 months to over 15 months, reducing fabric replacement frequency by 60%.

• Energy efficiency improved by 12% due to consistent air flow and faster drying.

• Paper quality enhanced with smoother finish and uniform moisture distribution.

• Operators reported zero unplanned shutdowns during the entire service period.

Customer Feedback

“The PPS dryer fabric from Yarns Technology has transformed our drying process. It runs stable under continuous high-temperature operation, reduces downtime, and produces a noticeably better paper surface finish.”
