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.ItemParameterRaw MaterialPBTDiameter0.05mm-0.30mmLength26mm and upBundle Diameter48-52mmMOQ200KGSBundle Diameter48-52mmApplicationToothbrush, Face brush,Washing brush,Industrial brush,etc.PackageN.W 10kg/CTN, G.W.12kg/CTNCarton Dimension40*40*25cmPBT Monofilaments Properties- Excellent stiffness in wet or dry conditions-Excellent bend recovery-Low absorption in water-Good abrasion resistance-Excellent resistance to impact-Excellent resistance to organic solvents-Excellent resistance to heat-Excellent resistance to oxidation-More durability than nylon filamentsPropertiesPBTNylonWater Absorption,24hr(%)0.083.0Bend Recovery(%)9490Mold Shrinkage(%)1.71.1Crimp Rigidity(%)43.722.4Dimension Stability in wet anddry conditions(%)01.5Initial modulus(cN/dtex)2.42.42.1Dendity(g/cm3)1.351.14Melting Point(ºC)224210
