Material
Fiberglass Filament
Fiberglass Filament is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. Do not select stiffness from the material name alone. Specify filament diameter, free trim, density, grade, and service conditions as one set.
Material Overview
Fiberglass Filament is a glass fiber filament used as brush fill or a cleaning-contact element.
In a finished brush, Fiberglass Filament does not create a fixed stiffness by itself. Contact force and recovery depend on filament diameter, free trim, density, tuft pattern, and installed interference. Grade, moisture, temperature, and chemistry affect how that behavior changes in service.
