Most people are more familiar with this as Teflon. PFA is called Perflouroalkoxy. They are a bit similar to each other, but you can tell what you are looking at based on their appearance.

PFA stands for Perfluroalkoxy and PTFE is the acronym for Polytetrafluoroethylene. PFA and PTFE have many similar properties for they are not the same. PFA is a type of fluoropolymer many used in plastics. It is more flexible than PTFE. PFA is not as chemical and temperature resistant as PTFE. Its operating ranges in temperature are from -200 to 260 degree Celsius. PTA can be melted and processed; it is done through mold injections.

Because of its chemical properties and its transparency, PTFE is a synthetic polymer that is mostly known as “Teflon”. It is more resistant to heat compared to PFA. This is because of its wide range of operating temperatures. It typical operating temperature ranges from -270 to 260 degree Celsius. PTFE is also less affected by absorption of water. PTFE is often used in the production of fittings, gaskets, valve bodies and diaphragm. Hope you find this helpful.

PTFE is known as Polytetrafluoroethylene, and this is known as a synthetic fluoropolymer of tetrafluoroethylene. This is commonly used as a non-stick coating for pans and other pieces of cookware. This can make cooking easier and more fun for a lot of people. PTFE is sometimes used as a lubricant too.
