What Is a Teflon Seal?
A Teflon seal is a fluoroplastic material used to maintain sealing properties. It is also called packing or gasket.
Teflon has excellent chemical, electrical, and thermal properties. Because of its unique properties, Teflon is used as a sealing material in harsh conditions such as vacuum and high-pressure environments.
Uses of Teflon Seals
Teflon seals have excellent heat and cold resistance. Teflon seals also have good electrical properties and are highly resistant to various chemicals. Teflon's properties, which are not found in other industrial materials, allow it to be used in everything from vacuum to high-pressure environments.
For example, Teflon seals are used as gaskets to seal vacuum flanges and prevent atmospheric air from entering. Teflon seals are also used in hydraulic equipment to prevent leakage of fluids such as oil and water, in a wide range of applications from low pressure to high pressure.
Teflon seals are also used to prevent the intrusion of dust from outside (dust seals).
Principle of Teflon Seals
Teflon is a thermoplastic polymer (softens and can be molded by heat) composed of fluorine elements and carbon chains. Its unique chemical, electrical and thermal properties are due to the molecular structure of Teflon itself.
Fluorine is stably bonded to the carbon chains in Teflon. Therefore, it does not desorb even when heated up to a certain temperature, and its properties as Teflon are hardly lost. However, the melting point of Teflon is 327°C. Above this temperature, Teflon becomes gelatinous, and its mechanical properties drop sharply.
In addition, Teflon is extremely stable against acids, alkalis, and organic solvents, and rarely corrodes or swells. It also exhibits strong resistance to ozone gas. In addition, Teflon has no electrical polarity (non-polarity) due to the symmetry of its molecular structure.
Therefore, parameters such as dielectric constant and power factor are constant regardless of temperature and frequency, and insulation resistance is extremely high. Even under high voltages of several tens of kV, the performance is maintained without loss of insulation properties.
