Polyamide 6 (PA6), commonly known as Nylon 6, is a versatile engineering polymer known for its excellent mechanical properties, thermal resistance, and chemical resistance. It is produced via ring-opening polymerization of caprolactam and widely used in automotive, industrial, and consumer applications. PA6 offers high strength, toughness, wear resistance, and low friction, making it ideal for gears, bearings, and structural components. It is also valued for its processability in injection molding, extrusion, and 3D printing. However, it has moderate water absorption, which can affect its dimensional stability in humid environments.
