The special material in the COG HygienicSeal series obtained some relevant approvals for application in highly demanding industries. As well as the harmlessness test according to FDA 21. CFR 177.2600, AP 306 is approved according to USP class VI in chapter 88 up to +121 °C and chapter 87. The EPDM compound also successfully passed the cytotoxicity test (according to ISO 10993-5:2009). This EPDM compound has extremely low migration values, which are particularly useful in applications in which there is a risk of contamination with the media to be sealed, e.g. in cell cultivation or insulin production. The high-performance material furthermore has excellent resistance to contact with CIP and SIP media and, in addition, is suitable for applications with WFI water. Owing to the operating temperature range from -40°C to +150°C, AP 306 is adaptable to the particular requirements of the production process.
