Nylon is also called polyamide, which contains dozens of varieties, including PA6, PA66, PA610, PA612, PA11, PA12, PA1010, PA46, PA6T, PA9T, and MXD-6. In the brush industry, the four PA6, PA66, PA610, and PA612 are the most commonly used, among which nylon PA612 brush filament is the best.Why is nylon PA612 brush filament so good? PA612 is a kind of nylon with good toughness. It is resistant to strong alkalis and weak acids and has a lower density than PA610. It has deficient water absorption, and its toughness, resilience, and abrasion resistance are better than PA6, PA66, and PA610. Therefore, the advantage of the nylon PA612 brush filament lies in its excellent wear resistance, slight molding shrinkage, hydrolysis resistance, and excellent dimensional stability.The primary purpose of nylon PA612 filaments is to make high-end toothbrush filaments, industrial equipment brush strips, and dust-proof brushes at the bottom of doors and windows. Although PA612 has the best flexibility and the highest cost, ordinary manufacturers cannot produce this brush filament. But don't worry, as long as we select brush filaments based on the product's characteristics, we can play the role of the brush and achieve the ideal use effect.
Due to the surrounding environment, most of us have skin problems. Staying up late, smog, ultraviolet rays, long-term makeup, etc., can cause acne, enlarged pores, sensitivity, blackheads, and other issues. At this time, we need to clean the face scientifically and use an electric facial cleansing brush with a soft facial cleansing brush filament. Because the diameter of the facial skin of the human body is about 180 microns, direct hand washing cannot clean the deep skin. If it is not treated in time, the oil will block the pores, which will cause a series of skin problems and destroy the skin barrier. When cleaning the face, you should use scientific methods and an electric facial cleansing brush to help. The critical role here is the soft facial cleansing brush filament. Usually, nylon filament and PBT filament are used to make ultra-fine 0.05mm brush filaments, and the brush filaments are rounded so that there will be no tingling sensation after deepening into the pores, so you can rest assured to do the cleaning work. The machine can take the soft facial cleansing brush filament with uniform diameter and moderate smoothness more smoothly. The filament transplanting does not get stuck in the machine and has higher efficiency. The cleansing brush made by this process has a slight sonic wave of 9000 times per minute. Under vibration, the filament is not easily deformed and will not fall off. On the other hand, moisten the filaments with warm water before cleaning; the filaments will be softer, the foam will be more prosperous, and the cleaning effect will be more significant.
When it comes to PBT brush filament, you know it is an economical alternative to nylon and cost-effective brush filament. Since everyone likes it so much, have you learned about it in depth? What are its performance characteristics? As a kind of economical brush filament, PBT has excellent toughness and hardness, elasticity, strong resilience and shock resistance, and good impact resistance. The raw material of PBT brush filament is milky white opaque particles, with a density of 1.30 to 1.32 g/cm3 and a melting point higher than nylon 6, at about 225°C. If it is resin, the heat distortion temperature is 55°C, and the heat distortion temperature of engineering plastics is 208 to 220°C. , And the long-term use temperature is 130 ℃. The water absorption rate of PBT brush filament is low, and the balance water absorption rate is 0.1%, which is more suitable for storage than nylon brush filament and suitable for working in the water environment. The diameter range of the PBT brush filament that Mingwang can produce here is 0.05-2.0mm. The brush filaments are often used in industrial brush rollers, nail polish brushes, toothbrushes, face wash brushes, eyelash brushes, vacuum cleaner brushes, etc. Some can also make strings, which are not easy to oxidize. The bending recovery rate of filament is more than 75%, and the bending recovery is excellent. If used as a functional brush filament, auxiliary materials can be added to make an antibacterial and antistatic PBT brush filament.
Good heat-resistant bristles are highly functional plastic bristles and are widely used in long-term high-temperature fields. They have excellent temperature resistance and excellent heat deflection temperature.What kind of material is used to produce such excellent and widely used heat Resistant bristles? There are two commonly used materials for heat Resistant bristles, namely PA66 and PA46. The melting point of the PA66 nylon filament is about 250℃. Compared with other nylon filaments, its heat deflection temperature is more advantageous. It is more commonly used in professional salon hair combs and steam iron brushes.The melting point of PA46 is even higher, at about 295℃. It still maintains excellent mechanical properties and excellent wear resistance under high-temperature conditions. PA46 brush bristle has better temperature resistance and heat deflection temperature than PA66 and has better toughness and abrasion resistance than nylon 66. The diameter range that Mingwang can make is 0.15mm or more. PA46 high-temperature resistant bristles are generally suitable for fields that require high heat resistance and fatigue strength.
