BrushMake's PA612 (Nylon 612) filament is a premium choice for high-quality toothbrushes. Its key advantages stem from its unique chemical structure:
Low Water Absorption: It absorbs significantly less water than other nylons like PA6 or PA66. This minimizes filament swelling, maintains bristle stiffness over time, and helps the brush head dry faster, creating a less hospitable environment for bacterial growth.
Superb Flexibility and Recovery: Offers excellent elasticity, allowing bristles to bend comfortably during use and then quickly spring back to their original shape, ensuring consistent cleaning performance and longevity.
High Abrasion Resistance & Durability: Resists wear from daily use and toothpaste abrasives, ensuring the bristles remain effective for the recommended lifespan of the toothbrush.
Excellent Chemical Resistance: Withstands oral environments and toothpaste ingredients without degrading.
These properties make PA612 filament perfect for manufacturing durable, hygienic, and high-performance manual and electric toothbrushes.
