Our 60%-90% PBT mini hollow blue tapered filament mixture imitation bristle is developed for paint brush makers who need a balance of elasticity, durability, and cost efficiency. 

With a high PBT percentage, the filament delivers stronger resilience and better shape recovery, helping brushes maintain performance during repeated use. 

The mini hollow structure supports good paint loading and controlled release, while the tapered tip improves brushing smoothness and finish quality. Customizable cut lengths from 44 mm to 114 mm make it suitable for different brush sizes and applications. 

Available diameters from 0.16 mm to 0.18 mm provide flexibility for softness and stiffness requirements. 

This filament mixture is an ideal alternative to natural bristle for consistent industrial production.
