Description PTFE is generally referred to as "non-stick coating"/"easy-cleaning material"; it is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents.
Application PTFE is widely used in various occasions where resistance to acid, alkali and organic solvents is required, and is used to make non-stick pans and dry-type transformers. Teflon has a soft texture, so it is often used for coatings. When it was first developed, its main application area was the inner wall coating of high-temperature launch rockets. PTFE is also the main component of the green tape.
Features And Benefits Corrosion resistance: It can withstand the action of all strong acids, strong bases, strong oxidants, reducing agents and various organic solvents except molten alkali metals, fluorinated media and molten strong bases.
Insulation: not affected by the environment and frequency, the resistivity can reach 1018 ohm·cm, the dielectric loss is small, and the breakdown voltage is high.
High and low temperature resistance: little change in temperature, wide temperature range, usable temperature -190~260 ℃.
Self-lubricating: It has the smallest friction coefficient among plastics and is an ideal oil-free lubricating material.
Surface non-stick: None of the known solid materials can adhere to the surface, and it is a solid material with the smallest surface energy.
Atmospheric aging resistance, radiation resistance and low permeability: long-term exposure to the atmosphere, the surface and properties remain unchanged.
Incombustibility: The oxygen limit index is below 90.
