Why Nylon 612 Is the Top Choice for Industrial Brush Filaments

2026 04/14

Industrial brush performance depends on filament material. Nylon 612, synthesized from dodecanedioic acid and hexamethylenediamine, is the industry’s preferred choice for high-end applications such as automotive manufacturing and electronic semiconductors.

Its core advantages:

1. Super wear resistance: Wear rate 30% lower than PA6/PA66; service life 2–3 times longer;

2. Low water absorption: Only 0.6%, ensuring excellent dimensional stability;

3. Strong resilience: Efficient cleaning and polishing without scratching workpieces;

4. Chemical resistance and certified safety.

Nylon 612 is versatile, easy to process, customizable, and now produced locally at high performance-cost ratio, replacing imports. It upgrades brush quality while lowering total costs, aligning with industrial high-end and green trends.

Tai Hing's PA (Nylon) 612 filament Fiber Filament has excellent mechanical properties, impact resistance, low-temperature properties, as well as the most chemically stabile in all type of Nylon filaments.
