Advanced Material Performance: PA612 delivers superior bend recovery and low water absorption for consistent wet stiffness; PBT provides exceptional chemical resistance to toothpaste abrasives and mouthwashes while maintaining bristle clarity.

Optimized End-Rounding: Precision-engineered filaments enable bubble-free, non-yellowing ball-tips through modern hot-air or mechanical rounding techniques, eliminating traditional epoxy while ensuring zero-tip detachment and maximum safety.

Hygienic Excellence: Smooth surfaces minimize bacterial adhesion while tapered profiles (0.10-0.25mm diameters) conform to gum lines and tooth contours for optimal plaque removal without irritation.
