Teflon (PTFE)
Teflon (PTFE), or polytetrafluoroethylene, is a high-performance fluoropolymer with unique properties for extreme conditions. It offers the lowest coefficient of friction of any solid material, is completely non-stick, chemically inert and withstands an exceptional range of −260 to 260 °C. It does not absorb water and is an excellent electrical insulator, ideal for the chemical, oil, electrical, pharmaceutical and food industries.

Note: PTFE is virtually inert and does not melt in the conventional way; it is processed by compaction and sintering. Natural/white color; values are for reference and may vary by grade. In engineering plastics, composition is identified by the base polymer, the process and its modifications, not by chemical percentages as with steels. The information and values in this data sheet are provided for reference only and may vary depending on manufacturing and application conditions. They do not constitute guaranteed specifications, so use and interpretation of this data is the user's responsibility.
