High Temperature Resistance Plastic PFA Used for Valve

                        High Purity Plastic PFA SHEET

Perfluoroalkoxyor PFA (comonly known as the soluble PTFE), it basically retained the properties of PTFE.

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(Perfluoroalkoxy), is a melt-processable fluoropolymer that combines many of the best traits of PTFE and FEP. 

Main properties of PFA sheet
• 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



PFA sheet applications:

1. Chemical tank liners
2. Semiconductor equipment components
3. Pump and valve parts
4. Electrical components
5. Medical devices parts
6. Food processing machinery components
7. Bearings \ bushings \washers
