ASEPCO’s EPDM Diaphragms
Patented Weirless Radial-Diaphragm™ Valve Design
|Ethylene propylene diene monomer (EPDM) is a Varox-cured material that is widely used in pharmaceutical and biotech applications. The material is non-cytotoxic and sulfur free. Like all of our diaphragm materials our EPDM diaphragms meet USP Class VI and FDA 21 CFR 177.2600 standards. It is black in color.
To get specific chemical compatibility information about EPDM and other elastomers, we suggest that you refer to the Cole-Parmer Chemical Compatibility Database.
