PFA Properties
   
          PFA (Perfluoroalkoxy)

Working Temperature: 500F (260C)
Color: Clear with light blue or tint
  • Excellent chemical resistance
  • Exceptional heat resistance
  • High light transmission
  • Extremely smooth surface
  • Long continuous lengths
  • Smoother and clearer than PTFE
  • Less permeable than PTFE
  • Increased flex life over FEP
 
The table below lists a generally accepted summary of properties that we believe to be reliable. Please note that many of these resins are produced in several varieties and property characteristics may vary. Therefore, determination of resin is dependent on the application and this table is only meant to serve as a general guideline.
