Material
HDPE Filament
HDPE Filament is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. The same material can produce different stiffness, so filament diameter, trim length, density, grade, and service conditions must also be defined.
Material Overview
HDPE Filament is used as brush fill or contact media where its property profile fits the cleaning duty.
In a finished brush, HDPE 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 | 0.10–2.50 mm |
|---|---|
| Hardness | Shore D 60–70 |
| Continuous temperature | 70–90°C |
| Peak temperature | 100–120°C |
| Water absorption | ≤0.01%（24h，ISO 62/ASTM D570） |
