Features | Description | Application |
---|---|---|
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. |
