What is PBT filament?

PBT (PolybutyleneTerephthalate)

PBT filament has excellent performance of toughness,abrasionresistance,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 Monofilament 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 filaments
