<p>In the production of brushes, the materials often used in the brush industry can be divided into four categories according to their materials: plastic brush filaments, animal hair, metal brush filaments, and plant fiber brush filaments.</p><p><br></p><p>Among them, the plastic wire also contains:</p><p>1. Nylon brush filament: Nylon brush filament is the most commonly used brush material, and it is a relatively good quality material among plastic brush filaments. Nylon filaments are relatively expensive. The main advantages of nylon brush filaments are:</p><p>a. Good elasticity: For example, there are a lot of wires in the electric box. In order to protect the wires, we need to use a brush to seal it. If we use a good elastic brush wire, the brush wire can maintain long-term elasticity under the pressure of the wire. To maintain its sealing effect, the relatively weakly elastic brush filament will be pressed to one side by the wire and cannot spring back to the original place, resulting in a gap, resulting in a poor sealing effect.</p><p>b. Strong abrasion resistance and light resistance: Compared with PBT, PP, PET, and PVC, brushes made of nylon filaments have much stronger light resistance and good aging resistance.</p><p>2. <a href="https://www.brushfiber.com/pbt-brush-filament-wholesale.html" rel="noopener noreferrer" target="_blank">PBT filament</a>: The density of PBT filament is greater than that of nylon filament, and its wear resistance and elasticity are closer to nylon filament, but the cost of PBT filament is lower, and the price of PBT filament is cheaper.</p><p>3. <a href="https://www.brushfiber.com/pp-brush-filament-material.html" rel="noopener noreferrer" target="_blank">PP brush filament</a>: Compared with PBT and nylon brush filament, PP brush filament has poor light resistance and aging resistance, and it is easy to deteriorate, age and harden under the conditions of sun exposure. The cost of PP brush filament is the lower of the three.</p><p>4. PET brush filament: PET filament has good processability. It is often used to make ordinary makeup brushes and wool brushes. It has the characteristics of good elasticity and softness. The skin feels good when makeup and the makeup effect is better. PET filament is not so soft. , The skin is not so comfortable during makeup.</p><p><br></p><p>Animal hair includes:</p><p>Pig hair: Pig hair is a very scarce brush material, and it is also a material that cannot be replaced by other materials, so pig hair is very expensive. Pig hair has good elasticity and has a particularly good effect on the fine grinding and polishing of products.</p><p>Wool: Wool can be used to make high-end cosmetic brushes. Wool is soft and feels comfortable to touch the skin. Wool is very expensive, so wool brushes are relatively expensive.</p><p>Horsehair: The raw materials are richer, and longer raw materials can be used. It is a good material for artistic brushes.</p><p><br></p><p>Metal brush wire includes:</p><p>Copper wire, steel wire: Copper wire and steel wire brushes are often used for metal surface polishing, rust removal and wood surface drawing treatment.</p><p><br></p><p>The common plant fiber <a href="https://www.brushfiber.com/" rel="noopener noreferrer" target="_blank">brush filaments </a>are:</p><p>Sisal silk: Sisal silk, also known as white brown silk, is a kind of plant fiber brushing silk. It has good adsorption properties and is often used for cleaning, grinding and polishing before dusting and painting in the assembly line.</p>
