What are the benefits of using PA610 filament for interdental brushes compared to other materials?

PA610 (Nylon 610) is exceptionally well-suited for interdental brushes. It offers superior tensile strength and excellent fatigue resistance, meaning the filaments can repeatedly bend without breaking. Its low water absorption rate ensures the filament maintains its structural integrity and cleaning performance in the moist environment of the mouth. This results in a brush that is both durable and gentle on gums.
