Tapered bristles are made of PBT (polybutylene terephthalate) filaments chemically treated to produce the unique tapered ends.

1.Desc.

PBT filament has excellent performance of toughness,resisting tiredness and shock. And its heat-resisting performance, climate-resisting performance, electric performance and bearing electric performance are good. Because of its moisture rate is low and color fastness, it’s very suitable for processing the brushes which are working in the wet environment.

Comparing with Nylon 612, it’s more economical,generally PBT filament is used for processing toothbrush, food-industry brushes, paint brush and cosmetic brush, etc.

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 toothbrush and cosmetic brush ,etc.
