Material
PVDF Filament
PVDF Filament is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. For a usable stiffness specification, provide the material, filament diameter, free trim, density, grade, and operating conditions.
Material Overview
PVDF Filament is a fluoropolymer filament used as brush fill or a cleaning-contact element.
In a finished brush, PVDF Filament does not create a fixed stiffness by itself. Working stiffness and recovery depend on filament size, free trim, density, tuft pattern, and contact. Grade and operating conditions determine how stable that behavior remains.
Material Properties
| Filament diameter | 0.10–1.50 mm; round or crimped monofilament |
|---|---|
| Temperature range | -40–140°C continuous service |
| Stiffness | Medium; stable wet stiffness |
