PFA
PFA is a co-polymer product of PTFE. The co-monomer perfluoroalkyl vinyl ether interferes in the crystallisability and molecular weight to achieve good mechanical properties and melt processability without sacrificing thermal performance and chemical resistance. The key advantage of PFA is its melt processability because of lower melt viscosity than PTFE.
Because of the high strength between Carbon, Fluorine and Oxygen atoms, PFA exhibits similar properties to PTFE over a large range of temperatures. Some other differences from PTFE are: Good permeability resistance because of lower void content and better deformation (Cold flow) resistance.

High-performance plastics serve a critical role in the Semiconductor industry by meeting the stringent requirements necessary for producing high-quality electronic components. Designed to withstand extreme conditions, materials such as PFA are invaluable in environments where traditional plastics would fail.
