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.PBT 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
