Solvent and Diaphragm Compatibility
Advanjet uses four different diaphragm materials: FKM (fluoroelastomers), silicone,
FFKM (perfluoroelastomers), and EPDM (ethylene propylene diene terpolymer). In
general, if the diaphragm material is incompatible with a solvent, the diaphragm will
exhibit slight swelling around the metal insert. If swelling occurs, the performance of the
jet will be adversely affected.
Use this table as a guide for selecting an appropriate cleaning solvent.
