Chemdyne® PP Membrane (Hydrophobic)

Polypropylene membrane filters offering the maximum in security, reliability and economy for critical filtration of solvents, corrosive chemicals and gases.

Chemdyne® filters are absolute rated membrane filters constructed of 100% pure polypropylene (PP). The PP membrane provides maximum chemical compatability, filtration performance, reliability and economy in a wide range of critical process applications. The highly porous membrane is inherently hydrophobic and provides wide chemical compatibility. Chemdyne® filters are available with virtually zero sodium or trace metal extractables.

What are the typical applications?
Chemdyne® meets the critical demand for contamination control in the chemical, microelectronics, aerospace, photonics, biologicals, pharmaceutical, cosmetics, and other industries. The Chemdyne® cartridge is designed for the removal of particulates, colloids and microorganisms from solvents, corrosive chemicals and gases. It also offers high security for bulk and point-of-use filtration.Typical chemicals include:
  • Acids
  • Bases
  • Alcohols
  • Solvents
  • Etchants
  • Photoresists
  • Photolithographic solutions
For aqueous solutions, the Chemdyne® filter must be pre-wet by immersion in a suitable low surface tension fluid. The inherently hydrophobic Chemdyne® filter is ideal for gas filtration applications which include:
  • Compressed air
  • Fermentation air
  • Pressurized gases
  • Tank ventilation
