|Nonstick Properties||PTFE coating creates a smooth and slippery surface that prevents adhesion of substances such as glue, adhesives, food, or chemicals.||It is ideal for applications such as cookware, bakeware, molds, conveyor belts, or release agents.|
|Low Friction||PTFE coatings have a low coefficient of friction, which reduces wear and tear, improves efficiency, and increases the lifespan of mechanical components.||It is commonly used in applications such as bearings, seals, slide plates, or machine parts.|
|Chemical Resistance||PTFE coatings are highly resistant to chemicals, solvents, and acids.||It is suitable for use in chemical processing equipment, valves, pipes, or containment vessels where contact with corrosive substances is common.|
|Heat Resistance||PTFE coatings can withstand extreme temperatures ranging from -200°C to +260°C (-400°F to +500°F).||It is suitable for use in high-temperature environments, such as oven trays, grills, heat exchangers, or insulation sleeves.|
