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:
