Parker Polyflow® Membrane

Polypropylene Membrane Cartridges for Microelectronics

Polyflow® Membrane cartridges are optimized for use in microelectronics applications such as bulk chemicals and photoresists. The all-polypropylene construction is an economical alternative to fluoropolymer-based cartridges.

Every cartridge is fabricated in a clean room environment, pre-flushed with 18 megohm-cm ultrapure DI water, and 100% integrity tested in an ISO-certified facility.


  • High-retention membrane
  • Wide range of conf gurations and ratings
  • 100% integrity tested


  • Bulk photoresist
  • Bulk electronics grade chemicals


Materials of Construction
Membrane:     Polypropylene
Support layers:     Polypropylene
Structure:     Polypropylene

All components are thermally bonded to ensure integrity and to reduce extractables.
