Black polytetrafluoroethylene PTFE film

Black PTFE film is a high-performance material that retains all the exceptional properties of PTFE while offering additional benefits due to its color and specific formulations. This material is widely used across various industries for its durability, versatility, and unique characteristics.

Key Properties

Chemical Resistance: Black PTFE film exhibits excellent resistance to virtually all chemicals, including acids, bases, and solvents, making it suitable for use in harsh chemical environments.

Thermal Stability: It can operate continuously at temperatures up to 260°C (500°F) and withstand short-term exposure to even higher temperatures. It also maintains its properties at cryogenic temperatures down to -265°C (-509°F).

Low Friction: PTFE has one of the lowest coefficients of friction of any solid material (static 0.08. dynamic 0.01), making it ideal for applications requiring minimal friction.

Non-Stick Properties: PTFE’s non-stick surface ensures that no substances adhere to it, even under high temperatures.

Electrical Insulation: The film has excellent dielectric properties, with a low dielectric constant (2.1) and high volume resistivity (>10¹⁷ Ω·cm), making it suitable for electrical and electronic applications.

Mechanical Properties: Black PTFE film has a tensile strength of 22 MPa and an elongation at break of 220%, ensuring flexibility and durability.

Color Stability: The black color of the film can provide additional benefits such as UV resistance and aesthetic appeal for certain applications.

Applications

Aerospace: Used in aircraft components, seals, and gaskets where high-temperature and chemical resistance are essential.

Automotive: Ideal for engine components, seals, and bearings that require high-temperature resistance and low friction.

Chemical Processing: Black PTFE film is used in chemical reactors, valves, and piping systems due to its resistance to corrosive chemicals.

Electronics: Used in high-voltage insulators and components due to its excellent electrical insulation properties.

Industrial Applications: The black color can provide additional UV resistance, making it suitable for outdoor applications.

Food Processing: While white PTFE is more common in food-grade applications, black PTFE can also be used in certain food processing equipment where non-stick properties are required.
