Polytetrafluoroethylene (PTFE) sheet is a polymer synthetic material made from polytetrafluoroethylene resin through a process of molding, sintering, and cooling. Known as the "King of Plastics" for its diverse properties, PTFE has seen increasing demand across a wide range of applications in recent years.
This product offers exceptional performance characteristics.
It exhibits exceptional stability across a wide temperature range, operating stably and reliably over extended periods of time within a wide temperature range of -180°C to 260°C. Even short-term exposure to higher temperatures shows no degradation.
Its corrosion resistance is exceptional, withstanding the erosion of a wide range of corrosive media, including strong acids, bases, and organic solvents, with the exception of a few substances like molten sodium and fluorine. It excels in chemical corrosion protection.
Furthermore, its coefficient of friction is as low as 0.04, the lowest among known solid materials. Its surface is also highly non-sticky, making it less susceptible to adhesion to other materials.
It also possesses excellent electrical insulation properties, with a stable dielectric constant, maintaining good insulation even in high-frequency electric fields, making it an ideal material for the electrical and electronic fields.
Thanks to these excellent properties, polytetrafluoroethylene sheet has a wide range of applications.
In the chemical industry, it is often used to make components such as reactor linings, pipelines, and valve gaskets, effectively addressing the corrosion problem of traditional materials and extending the service life of equipment.
In mechanical manufacturing, it is used as wear-resistant, self-lubricating components such as bearings and sliders, reducing friction loss during equipment operation and lowering maintenance costs.
In the electronics industry, due to its excellent insulation properties, it is widely used in high-frequency cable insulation and capacitor dielectrics. In the food processing industry, due to its non-toxic and non-stick properties, it is often used in food conveyor belts and mold linings, ensuring the safety and hygiene of food production.
In the medical field, its excellent biocompatibility is used in the manufacture of implantable medical devices such as artificial blood vessels and heart valves, bringing benefits to patients.
With the continuous advancement of industrial technology, the application prospects of polytetrafluoroethylene sheet will continue to expand, providing strong support for the upgrading and development of various industries.
