POM-H (Acetal Homopolymer) vs PTFE (Teflon)
Side-by-side chemical composition and mechanical property comparison.
Overview
POM-H (Acetal Homopolymer)
Polyoxymethylene Homopolymer — slightly stronger and stiffer than POM-C copolymer but with centerline porosity in stock shapes and lower resistance to hot water/alkalis. Trade names include Delrin (DuPont/DuPont de Nemours) and Tenac (Asahi Kasei). Used for gears, cams, springs, clips, fuel system components, and precision-machined parts where maximum stiffness is needed.
PTFE (Teflon)
Polytetrafluoroethylene — the most chemically resistant polymer. Lowest friction coefficient of any solid material (~0.05-0.10). Service range -240°C to +260°C continuous. Cannot be melt-processed — must be sintered from powder (like ceramics). Very low mechanical strength. Trade name Teflon (Chemours/DuPont). Used for seals, gaskets, bearings, non-stick coatings, chemical reactor linings, electrical insulation, and lab equipment.
