The seal manufacturer C. Otto Gehrckens has developed the EPDM compound “AP 307” for highly sensitive production processes in the food and pharmaceutical industries, biotechnology and medical technology. Key approvals for applications in these highly demanding sectors have been obtained for this special material in the COG HygienicSeal series.
High resistance in CIP/SIP processes
In addition to the safety assessment according to FDA 21 CFR 177.2600, AP 307 has been approved according to USP Chapter 87 and USP Chapter 88 Class VI up to +121 °C. The EPDM compound has also passed the cytotoxicity test (according to ISO 10993-5:2009). The extremely low migration values of this EPDM compound are particularly relevant for applications where there is a risk of contamination with the media being contained by the seal, for example, in cell cultivation or insulin production. The high-performance material is extremely resistant in contact with CIP and SIP media, and also suitable for applications with aggressive water for injection (WFI). With an operating temperature range of -40 °C to +150 °C, AP 307 has the flexibility to meet special requirements in the production process.
