The all-around performance of PBT brush filament is similar to that of nylon brush filaments and is known as an economical substitute for nylon filament. It has excellent toughness and impact resistance, good acid and alkali resistance, low moisture absorption, and is suitable for wet working environments.
The PA brush material is more expensive, but the performance of the bristle is strong and stable. What about the performance of PBT, which is second only to PA brush filament? PBT brush filament has high breaking strength and elastic modulus, stable heat setting; low moisture absorption rate, suitable for the wet working environment, commonly used in processing toothbrushes, industrial brushes, cleaning brushes, nail polish brushes, etc.; its tensile properties and toughness are not only good but also suitable for making strings.
Using it to make nail polish brush filament is a relatively affordable choice. PBT brush filament for nail polish brush has good elasticity, good wear resistance, good recovery, and no water absorption. Improved efficiency, high straightness of the brush filament is conducive to make brushes.
