Material
PA11 Nylon
PA11 Nylon is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. To define stiffness, confirm the material together with filament diameter, free trim length, density, grade, and service conditions.
Material Overview
PA11 Nylon is used as brush fill or contact media where its property profile fits the cleaning duty.
In a finished brush, PA11 Nylon does not create a fixed stiffness by itself. The final contact depends on filament diameter, free trim, density, tuft pattern, and interference; moisture, heat, and chemicals can change the response.
Material Properties
| Filament diameter | 0.05–2.00 mm |
|---|---|
| Hardness | Shore D 65–75 |
| Continuous temperature | 80–100°C |
| Peak temperature | 120–140°C |
| Water absorption | 0.3–0.6%（24h，ISO 62/ASTM D570） |
