Teflon Film

Thermal stability: PTFE maintains its properties across an impressive temperature range, from -200°C to 260°C. It has a melting point of 327°C and can withstand short-term exposure up to 300°C. This makes it ideal for aerospace and industrial applications involving extreme temperatures.

Chemical inertness: Resistant to nearly all acids, bases, and solvents, PTFE has extremely low permeability to gases and liquids. This characteristic is crucial in chemical processing and storage applications where material integrity is paramount.

Electrical insulation: With a dielectric constant of 2.0 (at 1 MHz), dielectric strength exceeding 200 kV/mm, and volume resistivity over 10^18 Ω·cm, PTFE is an excellent electrical insulator. It's widely used in high-frequency and high-voltage electrical applications

Low friction: PTFE's film coefficient of friction ranges from 0.05 to 0.10, making it exceptionally slippery. This property is beneficial in applications like sliding bearings, gaskets, and seals where reducing wear is crucial.

Mechanical strength: Despite being relatively soft, PTFE offers sufficient strength for many applications. It has a tensile strength of 20-30 MPa, elongation of 200-400%, and a Shore D hardness of 50-55.

Non-stick surface: PTFE's very low surface energy makes it difficult for other substances to adhere to it. This property is famously utilized in cookware and industrial processes where material build-up must be minimized.

Weather and UV resistant: PTFE film exhibits excellent resistance to weathering and UV radiation, maintaining its properties over time even when exposed to harsh environmental conditions. This makes it suitable for long-term outdoor applications.
