Abrasive grit encapsulated into extruded nylon filament enables an abrasive nylon strip brush to perform more aggressive cleaning from a static position. Abrasive nylon as a fill material in strip brushes provides you the flexibility and conformability of a brush, while also giving you the benefits of an abrasive. You can select grit size in tandem with the filament diameter to control the aggressiveness of the cleaning action and the stiffness of the filament.
