PA6 GF30 vs PA6 (Nylon 6): Same base polymer — GF30 doubles strength and triples stiffness
PA6 GF30 vs PA6 (Nylon 6)
Side-by-side chemical composition and mechanical property comparison.
Overview
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.
PA6 (Nylon 6)
Polyamide 6 (Nylon 6) — the most widely used engineering thermoplastic. Excellent combination of mechanical strength, toughness, wear resistance, and chemical resistance. Properties are moisture-sensitive — 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.

Compatibility Assessment
PA6 GF30: UTS 175 vs 80 MPa, E-Mod 9.5 vs 3.0 GPa, HDT 200 vs 70°C. But GF30 has only 3% elongation (vs 50+%), is anisotropic (fiber orientation matters), and abrades mating surfaces. Choose GF30 for structural metal-replacement; unfilled PA6 for impact/wear/sliding parts.
