PFA 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.

PFA offer similar properties to that of FEP but is considered more of a premium resin.  PFA coating is ideal when extended services are required in hostile environments involving chemical, thermal and mechanical stress.


Properties of PFA :

• High melting strength
• Stability at high processing temperatures
• Excellent crack resistance
• Excellent stress resistance
• 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 coatings that are applied on carbon steel or stainless steel have a continuous service temperature ranging between -60˚F to 400˚F.  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.

What is PTFE ?

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer containing numerous applications.  PTFE coating has a very low coefficient of friction and is used as a non stick coating in various applications.  It is also said to be a non reactive coating and hence, it is used in containers, pipe work for reactive and corrosive chemicals.

PTFE is a fluorocarbon solid.  PTFE is available in aqueous based form.  It is a high molecular weight compound consisting of carbon and fluorine.  If PTFE is used as a lubricant, it can reduce friction, wear and energy consumption of machinery.

PTFE is a white solid at room temperature with a density of about 2.2g/cm square.  The coefficient friction of plastics is usually 0.1 or less.  It is known as the second lowest coefficient friction of solid materials.  PTFE has excellent dielectric properties.  It is truly ideal at high radio frequencies.

PTFE coatings and its variants have become a solution for many problems that are associated with modern manufacturing and material handling.  PTFE coatings are ideal for food processing, food packaging, chemical protection and can also be used as a dry lubricant in place of oils.  The ideal performance of PTFE coating will depends on its grade selection.

PTFE industrial coatings can be applied to steel, alloy, brass aluminum and some special materials like Inconel. For perfect adhesion, the substrate required abrading to secure a good bond between the PTFE and the material.

PTFE coated materials have the highest operating temperature of any fluoropolymer and can be operated at 260˚C.

PTFE coatings are designed by us in such a way to suit many different applications of API and chemical equipment.  We offer PTFE coatings that are strong enough for all the applications that are required by the customer.

PTFE coatings can be used in a wide range of industries including electrical, mechanical, food processing, food packaging industries and even for some scientific and marine applications.


Ideal features of PTFE :

• Strength
• Chemical inertness
• Excellent dielectric properties
• Lowest coefficient of friction
• Bio compatibility
