Material
PPS Filament
PPS Filament is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. For brush stiffness, do not give only the material name. Filament diameter, free trim, density, grade, and service conditions must be specified together.
Material Overview
PPS is a semicrystalline engineering polymer with low moisture uptake and strong grade-dependent chemical and thermal performance.
In a finished brush, PPS Filament does not create a fixed stiffness by itself. Contact performance comes from the filament geometry and installed setting; grade, moisture, heat, and chemistry determine how it performs over time.

Frequently Asked Questions
What are the key properties of PPS Filament brush material?
PPS is a semicrystalline engineering polymer with low moisture uptake and strong grade-dependent chemical and thermal performance. Direct data: Density: 1.34–1.36 g/cm³; Melting point: 280–285°C; Water absorption: below 0.05%; Continuous service: up to 200°C; Filament diameter: 0.10–1.20 mm.
Where is PPS Filament used in cleaning brushes?
Hot chemical-process rollers, strip brushes and tube brushes that need dimensional stability beyond nylon or polyester.
How does filament geometry change PPS Filament brush stiffness?
PPS Filament changes brush stiffness through filament diameter, free trim, density, crimp, and contact. Use finer filament and longer trim for conformable contact; use coarser filament, shorter trim, or higher density for stronger displacement or cutting.
When should PPS Filament be replaced by another material?
Compare PPS Filament with Nylon, PBT, PET. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
