| 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. |
| 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. 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 |
