Micro Seals - Small Scale, Big Impact

High-quality materials and customized solutions

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.

This variety of materials makes it possible to develop customized sealing elements for a wide range of medical applications where precision and hygiene are crucial. “Our customers demand very small components that are not only extremely precise but also meet the highest standards of durability and hygiene,” explains Tobias Gutsch, Product Manager, Division Special Sealing Industry at Freudenberg Sealing Technologies. “Our Micro Seals meet these requirements thanks to advanced manufacturing technologies and our unique material expertise. The high durability and reliability of our products play a major role in ensuring the smooth operation of devices even in critical applications.” Critical applications are ventilators, anesthesia systems and highly sensitive analysis devices.

Global standards and certifications

Freudenberg Sealing Technologies manufactures its Micro Seals in line with the strictest international standards to meet the high demands for precision, hygiene and durability. They must withstand extreme conditions while performing reliably at all times, especially in critical medical applications. To ensure this, the components meet all the relevant hygiene standards, including ISO 13485 for medical devices and FDA compliance in the United States. This guarantees that the products deliver precise control and sealing performance in sterile environments, contributing to the safety and functionality of vital systems.
