What is the PTFE Sheet and Its Application Area?

PTFE sheets are manufactured from pure PTFE through a series of processes including molding, cutting, and machining. These sheets exhibit great heat resistance, capable of withstanding temperatures from -180°C to +250°C. They also offer good electrical insulation properties, unaffected by temperature and frequency variations. PTFE sheets are characterized by their non-stick, non-flammable, and water-repellent nature. The resin used to create these sheets is typically processed through molding and sintering, resulting in rods, sheets, or other profiles that can be further machined using lathes, drills, and mills. By stretching the rods through machining, oriented films can be produced.

PTFE sheets boast good chemical resistance among plastics, showing no signs of aging and maintaining their electrical insulation properties. They also have a low coefficient of friction.  The good chemical resistance of PTFE has made it a popular choice for fillers and seals, addressing numerous challenges in the oil, chemical, pharmaceutical, and other industries.

PTFE sheets find use in a multitude of sectors, including:

- Mechanical, construction, and transportation industries for components like sliding blocks and guide rails.

- Printing and dyeing, light industry, and textiles as anti-stick materials.

- Chemical, storage tanks, pharmaceutical, and dye industries for corrosion-resistant linings in containers, reactors, and large pipelines.

- Aviation, military, and other heavy industries.

PTFE is also called PTFE board and Teflon sheet, with the structural formula -[-CF2-CF2-] n -, it is a polymer derived from tetrafluoroethylene. It is renowned for its chemical stability and corrosion resistance. PTFE, also known as PTFE or F4, is hailed as a corrosion-resistant material, earning it the nickname "the king of plastics."
