Brush can be well understood in Chinese, the material is the“filament”,the function is cleaning, polishing, abrasing, sealing, dust-proof, fitering and so on. It means that the most important part of the brush is the“filament”.Generally speaking, the brush is made by animal hair, plant fibre, plastic, wire or abrasive filaments. The cost of Animal hair is more expensive, and the plant fibre is worn easily. Wire and abrasive filaments are always used in industry. The plastic is in common use and much more cheaper among all the material, including PA/PP/PBT/PE/PET. But PBT / PE / PET has slightly toxic, PA / PP is non-toxic. Therefore, many customers choose PP/PA as the filament. But PA is the best choice between PP and PA.
