PTFE (Teflon) Material Guide: Properties, Alternatives & Comparisons
PTFE (Polytetrafluoroethylene), commonly known as Teflon, is one of the most versatile fluoropolymers in industrial applications. With its exceptional chemical resistance, ultra-low friction coefficient, and outstanding dielectric properties, PTFE is the benchmark material for seals, gaskets, bearings, and non-stick surfaces. This comprehensive guide covers PTFE properties, alternatives, and head-to-head comparisons with other engineering plastics.
