Chemical anti-corrosion PFA sealing, ring and gasket
PFA ( Perfluoroalkoxy )
PFA (commonly known as soluble PTFE). In terms of its properties, this polymer is similar to PTFE. The big difference is that the alkoxy substituents allow the polymer to be melt-processed. It has improved flow, creep resistance, and thermal stability close to or exceeding PTFE.
Features:
1. Good folding and cracking resistance
2. High mechanical strength, 1.6 times of PTFE or more
3. Outstanding high/low temperature resistance
4. Chemical stability, electrical insulation
5. Self-lubrication, non-sticky
6. Good UV stability
7. Flame retardant, Abrasion resistant
8. FDA compliant grades available
Typical Applications:
1. Chemical tank liners
2. Pump and valve parts
3. Semiconductor components
