PPS Filament
High-performance polymer filament
PPS is a high-temperature, chemical-resistant polymer filament used where nylon and polyester soften: oven bands, hot molds, sealing jaws and hot process rollers. It keeps its shape and takes up almost no water. It costs more than common fills and is only worth it where the heat really calls for it.
What is PPS filament?
PPS, polyphenylene sulfide, is a semicrystalline engineering polymer. As filament it has a density of 1.34–1.36 g/cm³, melts at 280–285°C and takes up less than 0.05% water. It is drawn from about 0.10 mm to 1.2 mm.
How hot can a PPS brush run?
For brush service, about 200°C continuous. Some PPS resin grades are rated higher; Ensinger, for example, lists 230°C long-term service for specific TECATRON grades. A resin or stock-shape rating is not automatically a filament or a finished-brush rating, so the filament grade and the brush assembly are confirmed for the job. Our PPS/Cornex mold brush works on surfaces up to 200°C with PPS, or 270°C with Cornex fill.
Where is PPS used?
In our range: oven band brushes, sealing jaw cleaning brushes for packaging machines, PPS/Cornex brushes for hot molds and die-casting equipment, and a paper machine roller. All of them touch hot surfaces where nylon would soften or melt.
Which chemicals suit PPS?
PPS is broadly chemical resistant, but not universally. Check the grade against the exact chemical, concentration, temperature, exposure time and load before specifying it for a chemical process.
Where does PPS fall short?
Cost, and it is stiffer and less springy than nylon. Where moderate-temperature nylon, PBT or PP meets the duty, PPS adds nothing. Above its range, PEEK, Cornex or wire take over.
What should you tell us when you ask for a PPS brush?
The surface temperature, steady and peak, how long the brush touches it, the deposit, any chemicals, and the core and holder materials, which must take the same heat.
Questions buyers ask about PPS Filament
What temperature can a PPS brush handle?
About 200°C continuous for brush service. Some PPS resin grades are rated higher, but the filament and the finished brush are confirmed for the job, including the core and holder.
Which brush fill works on a hot oven band or sealing jaw?
PPS, where the surface stays within about 200°C. For hotter surfaces, Cornex fill, PEEK or wire. Tell us the surface temperature and contact time.
Why not just use nylon on hot parts?
Nylon softens and loses its spring well below PPS's limit, and it can melt on hot surfaces. PPS costs more but keeps its shape where nylon would fail.

Discuss This Material
Share what the brush works on, the temperature and chemicals it meets, the form you need — strip, disc, roller or hand brush — the quantity and a drawing or photo.
We reply to every request within 24 hours, with a quotation or with the questions we need answered first. If the brush can be made on our existing tooling, we make the sample directly. If it needs new tooling, we quote a sample fee and a tooling fee, and the sample fee is credited against the bulk order. Need an NDA first? We sign yours before you send drawings, and the files you send are never shown to other customers.
