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.

What does FDA compliance mean for molded rubber parts?

01. June 2020

Molded rubber parts are used in many sensitive applications, and as such potentially could have a direct effect on the health of humans. Customers with business in the food sector have special requirements both for the molded rubber parts and the materials that go into making them. FDA compliance is important in this sector. It is also mandatory. The Food and Drug Administration (FDA) is the USA’s federal agency responsible for protecting public health. Its provisions function to ensure the safety of products intended for the American market. However, its regulations are also recognised globally. In this blog post, we will take a closer look at the FDA and examine the significance of FDA compliance in the manufacture of molded rubber parts.
