What is the difference between PP, PET, and PVC broom filaments?

PP, PET, and PVC broom filaments serve different sweeping needs, so the best choice depends on the cleaning environment, required stiffness, and product positioning.
PP is a lightweight option commonly used for garden brooms and rough outdoor surfaces.
PET is suitable for applications requiring firm support and wear resistance, including garage and patio brooms.
PVC is used for indoor household brooms where flexibility and everyday dust collection are important. 
These are starting points rather than universal rules; actual performance also depends on filament diameter, shape, and broom design. Manufacturers should compare samples under their intended cleaning conditions before choosing a material for mass production.
