Natural white polytetrafluoroethylene PTFE Teflon film

Natural white PTFE (Teflon) film is a high-performance material known for its exceptional properties, making it suitable for a wide range of applications. Below are the key characteristics and applications of this material:

Key Properties

Chemical Resistance: PTFE film exhibits excellent resistance to virtually all chemicals, including acids, bases, and solvents.
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: PTFE film has a tensile strength of 22 MPa and an elongation at break of 220%, ensuring flexibility and durability.

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: 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.
Food Processing: White PTFE film is FDA-compliant and suitable for food-grade applications due to its non-stick and easy-clean properties.
Medical Devices: Suitable for medical implants and devices due to its biocompatibility and non-stick properties.
