PTFE (Polytetrafluoroethylene) is a high-performance fluoropolymer known for its unique combination of physical, chemical, and thermal properties: Chemical resistance: Inert to almost all chemicals, including acids, bases, and solvents. Thermal stability: Operates across a wide temperature range, from –200 °C to +260 °C (–328 °F to +500 °F). Low friction: Exhibits one of the lowest coefficients of friction among solid materials, ideal for non-stick and sliding applications. Non-stick surface: Prevents adhesion of particles and contaminants, commonly used in non-stick coatings. Non-reactive: Highly resistant to chemical reactions, oxidation, and UV exposure. Electrical insulation: Excellent dielectric properties, even at high frequencies and temperatures. Hydrophobic and oleophobic: Repels water and oils due to low surface energy. Biocompatibility: Safe for use in medical and food applications, available in FDA-approved grades. Low mechanical strength: PTFE is relatively soft and prone to cold flow (creep), but can be reinforced with fillers like glass fiber, carbon, or bronze for improved performance. These properties make PTFE ideal for applications in sealing, chemical processing, aerospace, electrical insulation, and food technology.
