China Double Colors PBT Tapered Filament

PBT Tapered Filaments with colored tips
Tapered bristles are made of PBT filaments chemically treated to produce the unique tapered ends. The tip of monofilament is dyed color different from the rest of monofilament.
Tapered bristles are made of PBT (polybutylene terephthalate) filaments chemically treated to produce the unique tapered ends. PBT tapered filament is divided into single tapered PBT filament and double tapered PBT filament. Single tapered PBT filament is used for processing paint brush. And Double tapered PBT filament is used for processing tooth brush and cosmetic brush ,etc.
PBT (Polybutylene Terephthalate)
PBT 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.PBT filament can be sterilized at extremely high temperatures, it is suitable for food-industry brushes. Comparing with Nylon 612, it's more economical, and always being perfectly substituted in toothbrushes or cosmetic brushes.
