PFA sheet / PFA Plate
Perfluoroalkoxyor PFA (comonly known as the soluble PTFE), it basically retained the properties of PTFE.
Such as outstanding high&low temperature resistance, chemical stability, electrical insulation, self-lubrication, non-sticky and high mechanical strength properties. It differs from the PTFE Resins in that it is melt-processable using conventional injection molding and screw Extrusion techniques. It's with good folding and cracking resistance, and the mechanical Strength is around 1.6times of PTFE or more.
Main properties of PFA
• Higher thermal stability than FEP
• Working temperature of up to 500º F (260ºC)
• Lower permeability than FEP
• Combines attributes of PTFE and FEP
• Translucent
• Maintains mechanical strength at high temperatures
• Moisture absorption close to zero

- Bearings \ bushings \washers
PFA properties are similar to FEP in terms of its mechanical properties. These two are both superior To PTFE with regards to their flexibility, making them useful for tubing applications. However, their ability To endure repetitive folding (flex life) is actually lower than PTFEs own. PFA Plastic has a higher flex life Than FEP. PFA polymer is preferable to FEP where heat is concerned, but PTFE itself is slightly more Resistant to heat than both. PFA is more affected by water absorption and weathering than FEP, but is Superior in terms of salt spray resistance. Perhaps the most impressive feature of PFA material is its Electrical properties, as it features the dielectric constant of PTFE, and an almost identical dissipation factor, But a dielectric strength that is around four times higher. ETFE is effectively a high strength engineering version Of these three, and features what would likely be considered to be slightly degraded performance when compared With the other three.
