Material
Polyester / Nylon Blend Filament
Polyester / Nylon Blend 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
Polyester / Nylon Blend Filament is a mixed synthetic filament used as brush fill or a cleaning-contact element.
In a finished brush, Polyester / Nylon Blend 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.
