Teflon O-rings – PTFE
Teflon belongs to the family of thermoplastic materials and is a highly crystalline polymer formed through a free radical polymerization process of tetrafluoroethylene. The resulting structure is a linear molecular structure of carbon chains with two fluorine atoms.

Teflon excels in chemical resistance, high melting temperature, low coefficient of friction, and notable resistance to ignition and burning. It is generally used in applications where a long service life and extreme environmental conditions are required. Its properties can be enhanced by adding fillers and additives.

PTFE O-rings do not excel in high tensile strength compared to engineering plastics; however, they have impressive impact properties with high values, and they exhibit one of the lowest coefficients of friction among most plastics. Moreover, they are not considered a combustible material.

Teflon’s uniqueness lies in its ability to be used in mechanical applications across a very wide temperature range, from -200°C to +260°C. The chemical resistance of Teflon is exceptional in the presence of many organic materials and compounds, as well as in various solvents and strong acids and bases. Additionally, it has excellent insulating properties and a low dielectric constant, providing it with stability across its wide temperature range.

Teflon has a high melting viscosity temperature, which can be defined as extreme in comparison to other materials; therefore, it is challenging to process using conventional methods like extrusion or injection. Most processing methods are similar to those used for metallic and ceramic materials, such as compression under pressure of resin powder melted at high temperatures.

There are additional derivatives of Teflon, such as polytetrafluoroethylene, including fluoropropylene, fluorochlorine, and others. Their properties are very similar to those of tetrafluoroethylene, but they can be processed using conventional methods for thermoplastic materials.
