Freudenberg Sealing Technologies develops customized Micro Seals for medical technology applications
Freudenberg Sealing Technologies manufactures its Micro Seals from highly resistant elastomers such as FKM, FFKM and EPDM. These materials offer specific advantages depending on their application. FKM excels with strong chemical resistance and temperature stability up to 200 °C, which makes it an especially good choice for environments with aggressive media. FFKM offers extremely high chemical resistance and can reliably withstand temperatures up to 230 °C – an ideal material for the most demanding applications. EPDM, in turn, is particularly resistant to ozone, UV radiation and hot water and is well-suited for environments with high humidity or steam.
