PA6 (Nylon 6) vs PA612 (Polyamide 612): 0% composition overlap. Significantly different materials serving different application areas.
PA6 (Nylon 6) vs PA612 (Polyamide 612)
Side-by-side chemical composition and mechanical property comparison.
Overview
PA6 (Nylon 6)
Polyamide 6 (Nylon 6) β the most widely used engineering thermoplastic. Excellent combination of mechanical strength, toughness, wear resistance, and chemical resistance. Properties are moisture-sensitive β conditioned (50% RH) values are significantly lower than dry values. Trade names include Ultramid B (BASF), Akulon (DSM), Zytel (DuPont). Used for gears, bearings, bushings, cable ties, structural brackets, and automotive under-hood components.
PA612 (Polyamide 612)
Polyamide 612 β partially bio-based (dodecanedioic acid from palm kernel oil). Even lower moisture absorption than PA610 (~0.9% saturated vs ~1.4%). Better dimensional stability than PA6/PA66 in humid environments. Trade names: Zytel 151/158 (DuPont), Vestamid D (Evonik). Used for precision gears, cable ties, fuel system components, and monofilaments. Between PA610 and PA12 in the moisture/stiffness spectrum.
