What is PFA Coating?

PFA Teflon® is abbreviated as Perfluoroalkoxy Polymer Resin is a type of fluoropolymer with the properties almost similar to that of Polytetrafluoroethylene (PTFE). But it is melted using conventional injection molding and screw extrusion techniques. PFA coatings share the useful properties of PTFE as coefficient of friction and non reactivity but are easily formable.

We offer PFA Coating in two variants, (1) Regular PFA Coating which looks Black/Red Coloured and (2) Antistatic PFA Coating which is Black Coloured.

Ruby Red PFA Coating is having a special filler which improves permeance resistance of chemical compared to regular PFA coating hence it gives a better life.

PFA offer similar properties to that of FEP but is considered more of a premium resin. PFA coating is essential for equipment that need flexibility and reliability during continuous use at high temperature range, when extended services are required in hostile environments involving chemical, thermal and mechanical stress.

Properties of PFA Teflon® Liquid & Powder Coatings :

  • High melting strength
  • Stability at high processing temperatures, up to 400°F
  • Excellent crack resistance
  • Excellent stress resistance
  • Excellent stress resistance
  • UV resistant
  • FDA approved
  • Low coefficient of friction
  • More than 10 times flex life of FEP

PFA coating is not degraded by systems that are commonly encountered in chemical processes. It is inert to strong mineral acids, inorganic bases, inorganic oxidizing agents, salty solutions including some organic compounds as organic acids, anhydrides, aromatics, aliphatic hydrocarbons, alcohols, aldehydes, esters, ethers, chloro carbons, fluorocarbons and some combinations of the above.

PFA Teflon® coatings that are applied on carbon steel or stainless steel have a continuous service temperature ranging between -60℉ to 400℉. A primer is compulsory before applying the PFA coating. There is a little bit of draw back for PFA coatings, if ones damaged, they cannot be repaired. Heat is required to cure the coating.
