Materials for medical applications

18. January 2021

Impressive progress is continuously being made in medical research. Ever more sophisticated treatment methods are helping to alleviate or remedy the suffering of many people worldwide. In the field of medical technology, highly complex devices are developed and sophisticated systems are created to assist in the treatment of various diseases or injuries.

Molded rubber parts are highly important in medical technology. They are used there either as a standalone medical product or as a component of medical devices. As devices become more advanced, so do the demands placed on molded rubber parts and the materials used, which are often exposed to extreme temperatures and aggressive chemicals or medications. 

Which materials are particularly suitable and commonly used for medical device applications will be covered in this blog post. 

Hepako GmbH continues to grow

11. August 2020

Hepako GmbH, which specializes in the production of precision rubber parts, has expanded its site in Raisting, Germany. The extension on the existing site was completed in spring 2020. The operating area could thus be almost doubled.

FFKM (Perfluoro Rubber)

03. August 2020

When a molded rubber part has to withstand exposure to a highly aggressive chemical environment or perform well in high temperatures, FKM is your right choice. However, for some applications, even FKM reaches its limits and cannot be deployed due to exceptionally aggressive chemicals or extremely high operating temperatures. In these special cases, engineers and users turn to FFKM. This material that incorporates special perfluorinated monomers, in other words, entirely hydrogen-free monomers, has been developed to resist virtually all media, and withstand very high temperature stresses. It is known to many by the tradename Kalrez marketed by DuPont de Nemours.

In this blog post, we will be looking in some detail at the properties of FFKM and discuss how, even for FFKM, there can be important differences in its thermal and chemical performance.
