You may contact Sterlitech, they do supply membranes for different models.

As I am concerned Solvay provides PPSU polymer but not the PPSU membranes.

Repligen supplies both hollow fiber and cassette devices in both MF and UF ratings. PES Cassettes come from TangenX and Hollow fiber cartridges come from Spectrum. HF cartridges are available in both PS and PES depending on UF or MF.

Thanks for your answers. But if you ever come across the information of a PPSU membrane supplier please let me know.

PPSU is solvay product, i think no one making commercial membrane. Still in R&D i think. What kind of membrane you need.
