Key Features and Applications of PTFE Coating

Nonstick PropertiesPTFE 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 FrictionPTFE 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 ResistancePTFE 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 ResistancePTFE 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.
