Material
Antistatic PBT Filament
Antistatic PBT Filament is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. Material name alone is not enough to set stiffness; we also need filament diameter, free trim, density, grade, and working conditions.
Material Overview
Antistatic PBT Filament is used as brush fill or contact media where its property profile fits the cleaning duty.
In a finished brush, Antistatic PBT 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.
Material Properties
| Filament diameter | 0.03–1.00 mm |
|---|---|
| Hardness | Shore D 80–90 |
| Continuous temperature | 120–140°C |
| Peak temperature | 160–180°C |
| Water absorption | 0.05–0.25%（ISO 62/ASTM D570） |
Brush Applications
