PA11 (Polyamide 11) vs PA66 GF30: 0% composition overlap. Significantly different materials serving different application areas.
PA11 (Polyamide 11) vs PA66 GF30
Side-by-side chemical composition and mechanical property comparison.
Overview
PA11 (Polyamide 11)
Polyamide 11 — bio-based engineering thermoplastic derived from castor oil (ricinus). Lower moisture absorption than PA6/PA66 (0.9% vs 2.5-8%), better chemical resistance, and excellent low-temperature impact. 11 carbon atoms between amide groups = long aliphatic chain = more flexible/tough. Trade name: Rilsan (Arkema). Used for flexible tubing (automotive fuel/brake lines, pneumatic), offshore flexible pipes, powder coating, and SLS 3D printing (PA 2200 alternative).
PA66 GF30
Polyamide 66 with 30% short glass fiber — stronger and more heat-resistant than PA6 GF30 due to higher-Tm base polymer. UTS ~190 MPa dry, HDT ~250°C. THE automotive under-hood material for structural brackets. Trade names include Ultramid A3WG6 (BASF), Zytel 70G30 (DuPont), Durethan AKV 30 (LANXESS), Technyl A218 V30 (Domo). Used for engine brackets, radiator end tanks, air intake manifolds, and electrical connectors.
