PBT Nylon Oral Care Toothbrush Bristle Filament
PBT Solid Level Non-tapered Bristle Filament for Manufacturing of Toothbrushes
-Toothbrush Bristle
-Interdental Brush Filament
Product Description:
PBT toothbrush filament has excellent performance of toughness,abrasion resistance,low humidity absorption and color fasyness, And its heat-resisting performance, climate-resisting performance, electric performance and bearing electric performance are good. Because of its moisture rate is low, it’s very suitable for processing the brushes which are working in the wet environment. Comparing with Nylon 612, it’s more economical, and always being perfectly substituted in toothbrushes or cosmetic brushes.
PBT resin are melt-extruded into filaments, cooled in water, stretched, and annealed in hot-air chambers. These filaments have good dimensional stability, good bend recovery, and brilliant colors.
