PBT (Polybutylene Terephthalate)
PBT resin are melt-extruded into filaments, cooled in water, stretched, and annealed in hot-air chambers. These filaments have good dimensional stability, good bend recovery, and brilliant colors.
PBT Filaments
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.
PBT Monofilaments Properties
-Excellent stiffness in wet or dry conditions
-Excellent resistance to organic solvents
-Excellent bend recovery
-Excellent resistance to heat
-Low absorption in water
-Excellent resistance to oxidation
-Good abrasion resistance
-More durability than nylon filaments
-Excellent resistance to impact
