Volcanic Charcoal Dual Color PBT Tapered Toothbrush Filament
Volcanic Charcoal Dual Color PBT Tapered Toothbrush Filament
-Toothbrush Filament Bristle
Product Description:
Two-layered filament is an upgraded tapered filament,displaying different colors in the length and tip of the filament.This display adds a magical touch to the look of the product.Visual effect can be maximized by combinaton of two colors.
PBT Tapered Toothbrush filament 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.
PBT Tapered Toothbrush filament 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. PBT tapered filament is mainly used for manufacturing of tooth brush and cosmetic brush ,paint brush, Manicure brush,etc.
PBT filament is as polyester monofilament developed as an economical replacement for Polyamide (PA610 or PA612) in many applications.PBT filaments offer you improved abrasion resistance over Polyamide(Nylon).PBT filament is highly resistance to sunlight and absorbs very little water,So the PBT filaments can hold stiffness in wet applications. It has a better abrasion resistance than polypropylene(PP) or polystyrene（PS).
PBT filaments also has an excellent bend recovery,excellent solvent resistance and excellent odidation resistance at high temperatures, necessary for harsh conditions required for toothbrush manufacturing.

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.
