PA11 (Polyamide 11) vs PA6 GF30: 0% composition overlap. Significantly different materials serving different application areas.
PA11 (Polyamide 11) vs PA6 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).
PA6 GF30
Polyamide 6 with 30% short glass fiber reinforcement — the industry standard for metal replacement in structural injection-molded parts. UTS doubles vs unfilled PA6 (175 vs 80 MPa), stiffness triples (E-Mod 9.5 vs 3.0 GPa), and HDT jumps to 200°C+. The classic materialref.com differentiation case: Ultramid B3WG6 (BASF) = Zytel 73G30 (DuPont) = Durethan BKV 30 (LANXESS) = Akulon K224-G6 (DSM) = Grilon BG-30 (EMS) = Technyl C216 V30 (Domo) — all the same base material. Used for automotive brackets, engine covers, power tool housings, electrical connectors, and structural inserts.
