NBR (Nitrile Rubber) vs PA6 GF30
Side-by-side chemical composition and mechanical property comparison.
Overview
NBR (Nitrile Rubber)
Nitrile butadiene rubber (Buna-N) — THE oil and fuel resistant elastomer. ACN content (18-50%) determines the oil resistance vs low-temp flexibility tradeoff. Higher ACN = better oil resistance but stiffer at low temp. The most widely used seal material worldwide. Used for O-rings, fuel hoses, gaskets, hydraulic seals, oil seals, and nitrile gloves. Not suitable for ozone, UV, or polar solvents (ketones, esters). HNBR variant for higher heat resistance.
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.
