Description

SISTO-C Elastomer diaphragms bonded with TFM Manufactured in a specially developed process, these compo-site diaphragms 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. This material quality also complies with FDA specifications and the EU1935. The TFM’s excellent chemical and thermal properties make this diaphragm type the first choice for applications with chemically aggressive media and high temperatures. This diaphragm type is also recommended for use in media which need to be protected against rubber abrasion and fluids containing oils and greases. As the rubber is fully covered by the TFM sheet, even mechanical damage to the sheet does not result in cavity formation and therefore to undefined spaces which cannot be cleaned. This composite diaphragm is vacuum-resistant.
