PES vs PVDF
| PVDF (polyvinylidene fluoride) and PES (polyethersulfone) are types of filter membranes. They have similar molecular weight cutoffs and morphologies. However, they have different properties, including: |
|
| Oxidant resistance: | PVDF membranes have higher oxidant resistance than PES membranes. |
| Mechanical strength: | PVDF membranes have higher mechanical strength than PES membranes. |
| Hydrophobicity: | PVDF membranes are more hydrophobic than PES membranes. |
| Maximum flow rate: | PES membranes have roughly three times the maximum flow rate of PVDF membranes. |
| Fouling/removal efficiency: | PVDF membranes have higher fouling/removal efficiency than PES membranes. |
| Clogging: | PES membranes clog more slowly than PVDF membranes. |
