What advantages does PET filament offer for filter brush applications?

PET (Polyethylene Terephthalate) filament is the superior choice for filter brushes, especially in water treatment, pools, and industrial filtration. Its key advantage is exceptional resistance to hydrolysis (degradation in water), ensuring long-term performance in constantly wet conditions. It also boasts very high tensile strength and excellent resistance to weathering and abrasion, making it perfect for demanding automated cleaning systems.
