PBT Filament

Based on polyester PBT, it is a valid alternative to Nylon 612 in price driven market. It doesn’t absorb water keeping its performances in wet environment.

PBT NON-Tapered Filament(Generally PBT Filament)

Generally PBT filament is used for processing toothbrush, paint brush and cosmetic brush, etc.
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.
