What is PTFE Material?

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. Being hydrophobic, non-wetting, high density and resistant to high temperatures, PTFE is an incredibly versatile material with a wide variety of applications, though it's perhaps best-known for its non-stick properties.

The exceptional strength of the carbon-fluorine bond and a high molecular weight give PolyTetraFluoroEthylene (PTFE), a set of outstanding properties. Such properties include wide temperature use range of -180°C to +250°C. PTFE is resistant to virtually all corrosive chemicals and is suitable for almost all chemicals with the exception of fluorine, some fluorochemicals and molten alkali metals. The material is also recognised as remarkable in its resistance to flame. It is classified as a non-flammable material in air.

How Many Types of Filled PTFE Products

Filled PTFE products has more outstanding performance by adding filler such as carbon, graphite, bronze, glass fiber, carbon fiber, MOS2, PEEK, PI, POB BaSO4, SiO2,  glass bead, polyamide.

PTFE has excellent properties and is widely used in industrial sealing, electronics, chemical and other fields. VINDEC provides a wide range of PTFE plates, rods, tubes, case and CNC machining products.
