The GEMÜ Code 5M diaphragm has a two-piece design and comprises a PTFE face and a peroxide cured EPDM backing. An FKM backing is also available for highly permeating media (GEMÜ Code 5F). The PTFE used is a chemically modified second generation PTFE - called PTFE TFMTM. This material offers maximum chemical resistance and also features a considerably lower level of wear under steam conditions. In order to optimize the entire system in turn, both the PTFE face and the diaphragm backing are compounded for GEMÜ and manufactured within the GEMÜ Group.
