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.
