The bristles of nylon paint brushes are mainly made of nylon material. Nylon, also known as polyamide (Nylon), is a thermoplastic resin that contains repeated amide groups on its molecular backbone. In the brush making industry, commonly used nylon materials mainly include PA6 and PA66.
Nylon bristles have many excellent properties, including:
Good mechanical properties: nylon brush wear resistance, strong toughness, good bending recovery, long service life.
High temperature resistance: Nylon material can withstand higher temperatures, suitable for applications requiring high temperature resistance.
Strong water absorption: Nylon bristles can absorb many times their own weight of water, which is conducive to the dissolution of paint during cleaning.
Good environmental performance: nylon material is relatively environmentally friendly and will not cause too much pollution to the environment.
Moderate price: Although the cost of nylon material is relatively high, considering its excellent performance and service life, its price is still considered moderate.
In addition, nylon bristles also have good mold resistance, acid and alkali resistance, so that it can maintain stable performance in a variety of environments.
In the brush making process, nylon materials are usually made into bristles by specific processing processes, such as heating dissolution, mold extrusion, cutting, fixing and other steps to ensure the quality and performance of the bristles.
In summary, the bristles of nylon paint brushes are a material with excellent performance and wide range of uses, especially suitable for occasions requiring wear resistance, high temperature resistance, corrosion resistance and other characteristics.
