Teflon, whose main component is polytetrafluoroethylene (PTFE), has excellent high and low temperature resistance, chemical resistance, non-stick, electrical insulation, weather resistance, non-flammability and low friction coefficient. These characteristics make Teflon widely used in various fields, including kitchenware, industry, medical, electronics and aerospace. The following are the main characteristics of Teflon: 1. High and low temperature resistance: Teflon can remain stable at extreme temperatures, usually withstanding temperatures ranging from -190℃ to 260℃, and some can even reach 300℃. 2. Chemical resistance: Teflon has excellent resistance to a variety of chemicals, including strong acids, strong bases, organic solvents, etc., except for molten alkali metals, fluorinated media and strong bases, other chemicals have little effect on it. 3. Non-stick: The surface of Teflon is very smooth and not easy to adhere to other substances, which makes it an ideal material for applications such as non-stick pans and release agents. 4. Electrical insulation: Teflon has excellent electrical insulation performance, is not affected by the environment and frequency, has high resistivity and high breakdown voltage, so it is often used as an insulating material for wires and cables. 5. Weather resistance: Teflon can resist the influence of ultraviolet rays and various weather conditions, and is not easy to age even after long-term exposure to the atmosphere. 6. Non-flammability: Teflon has a low limited oxygen index, is not easy to burn, and has good safety. 7. Low friction coefficient: Teflon has a very low friction coefficient and excellent self-lubrication, making it an ideal oil-free lubricating material. 8. Superior surface smoothness: Teflon has a very smooth surface and has good wear resistance and durability. These characteristics of Teflon have made it widely used in many fields, bringing convenience and efficiency to life and industry.
