What is a PTFE coating?
PTFE is the original fluoropolymer. A fluoropolymer being a compound with a Fluorine atom in it. PTFE has excellent low friction properties and non-stick properties.
Although PTFE does have more porosity than other coatings in the fluoropolymer family as a rule, it does have a long and successful track record. Dry lubrication is a key performance area, either on its own or mixed with other dry lubrication coatings such as Graphite or Molybdenum Disulphide. PTFE is harder than its sister fluoropolymers PFA and FEP.
It’s chemical formula is shown below.
