SISTOAseptiXX TFM/EPDM bonded diaphragms

The elastomer diaphragms bonded with TFM are made of an FDA compatible EPDM rubber which is firmly bonded to a TFM film featuring improved mechanical properties and lower permeability compared with conventional PTFE.

The material quality of the EPDM and the TFM films complies with the specifications of FDA, EU1935, and USP. The TFM’s excellent chemical and thermal properties make this diaphragm type the first choice for applications with chemically aggressive and abrasive media as well as high temperatures.
