Teflon is a synthetic fluoropolymer renowned for its exceptional chemical inertness, non-stick surface properties, and low coefficient of friction. It is widely used in chemical processing equipment, cookware coatings, seals, gaskets, and electrical insulation where resistance to corrosion, extreme temperatures, and aggressive chemicals is critical. Engineers specify Teflon when conventional plastics fail due to chemical attack or when a low-friction, non-adhesive surface is functionally essential, though its relatively low strength and stiffness compared to structural plastics and its high cost limit use to applications where its unique properties justify the expense.
