Brush strips are widely used in our daily lives. There are a variety of brushes on the market that cannot be answered. How does the brush manufacturer distinguish whether the material of the brush is PP or PA?
Industrial brush strips are literally well understood. The material consists of "hair". The function is "brush", cleaning, polishing, polishing, sealing, dustproof, filtering and other functions.
The most important part of the brush is the "hair". Typical wool materials are animal hair, vegetable hair, plastic, metal wire and abrasive wire. Animal hair costs are high and plant hair is easily lost.
Wire and abrasive filaments are primarily used for industrial applications. The most commonly used and relatively affordable price is plastic, including PA / PP / PBT / PE / PET. PBT / PE / PET is slightly toxic, PA / PP is non-toxic and is the customer's first choice, while PA / PP is best for PA.
PP, polypropylene is also a thermoplastic polymer, acid and alkali resistant, but less flexible than PA, can also be made into hair of various diameters and colors, because of the acid and alkali can be used for medical purposes.
PA, nylon/nylon, which is a thermoplastic polymer, very wear-resistant, strong in elasticity, good in flexibility, good in recovery after twisting, and can be made into wool of various diameters and colors.
