NBR (Nitrile Rubber) vs PP 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.
PP GF30
Polypropylene with 30% short glass fiber — a cost-effective alternative to PA GF30 for applications up to ~130°C. Much cheaper base resin (PP vs PA), zero moisture sensitivity, and excellent chemical resistance. Lower strength than PA6 GF30 (UTS 80 vs 175 MPa) but sufficient for many structural parts. Trade names include Celstran PP-GF30 (Celanese), Tepex (LANXESS), Stamax (SABIC). Used for automotive front-end carriers, battery trays, HVAC components, and household appliance frames.
