PTFE (polytetrafluoroethylene) gaskets are made from a synthetic fluoropolymer that is chemically resistant, has a low coefficient of friction, and is hydrophobic. PTFE is also known by its brand name, Teflon. 

Here are some characteristics of PTFE gaskets: 

  • Temperature range

    PTFE gaskets can operate in temperatures ranging from -400°F to 500°F. However, at higher temperatures, PTFE decomposes into toxic and corrosive gases. 

  • Chemical resistance

    PTFE gaskets are resistant to most chemicals and are often used in applications where hygiene and non-contamination are important. 

  • Biocompatibility

    PTFE is considered biocompatible and physiologically safe, and is available in grades that are approved for use in the food industry and medical technology. 

  • Fillers

    PTFE gaskets can be reinforced with fillers like carbon or graphite to reduce creep under high pressures and temperatures. However, filled grades are not permitted in applications where they come into direct contact with food because they can discolor or taint foodstuffs. 

  • Thickness

    The thickness of a PTFE gasket depends on how it is produced. Skiving, which involves cutting a thin layer away from the surface of a cylinder of PTFE, produces a more consistent sheet.
