FKM (Fluoroelastomer / Viton) vs PA6 GF30: 0% composition overlap. Significantly different materials serving different application areas.
FKM (Fluoroelastomer / Viton) vs PA6 GF30
Side-by-side chemical composition and mechanical property comparison.
Overview
FKM (Fluoroelastomer / Viton)
Fluoroelastomer — THE high-temperature and chemical-resistant rubber. Outstanding resistance to oils, fuels, acids, and solvents at temperatures up to 200°C (short-term 230°C). Fluorine content (64-70%) determines chemical resistance. Trade names: Viton (Chemours), Tecnoflon (Solvay), Dai-El (Daikin). 5-10x more expensive than NBR. Used for aerospace fuel seals, chemical process seals, automotive fuel injector O-rings, semiconductor processing, and any seal exposed to aggressive chemicals at high temperature.
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.
