NBR (Nitrile Rubber) vs PA6-GF15
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-GF15
Polyamide 6 with 15% short glass fiber reinforcement — moderate stiffness increase (E-Mod ~5.5 GPa vs 2.7 unfilled) while retaining good impact strength and elongation. Better toughness than higher-filled grades (GF30, GF50). Trade names: Ultramid B3EG3 (BASF), Zytel 73G15 (DuPont). Used for structural clips, housings, brackets, and under-hood automotive parts where moderate stiffness with good impact is needed.
