Material
Polystyrene Filament
Polystyrene Filament is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. Brush stiffness depends on more than material. Filament size, exposed length, density, grade, and operating conditions all matter.
Material Overview
Polystyrene Filament is a synthetic filament used as brush fill or a cleaning-contact element.
In a finished brush, Polystyrene Filament does not create a fixed stiffness by itself. Filament diameter, trim length, density, tuft layout, and installed contact determine working force, while grade and environment affect durability and recovery.
Material Properties
| Filament diameter | 0.15–1.20 mm; straight or crimped |
|---|---|
| Temperature range | -10–70°C |
| Stiffness | Medium to firm; lower bend fatigue than nylon |
