Online-Seminar with sealing expert Stefan Bock The looming restrictions on the use of fluoropolymers in the wake of the PFAS debate serve as yet another call to developers and buyers to seek out long-term alternatives. In particular, manufacturers of valves and pumps for the beverage and process industries have so far found it difficult to
Online Seminar with Sealing Expert Stefan Bock 3M (Dyneon) recently announced that it will phase out all fluorinated compounds (PFAS) by the end of 2025. This will affect, among other things, all fluoropolymers relevant to sealing technology, such as PTFE (TF®, TFM®), FKM, and FFKM. Even aside from the PFAS issue, these materials are already
Online Seminar with Sealing Expert Stefan Bock Diaphragms for pumps and valves are often made of PTFE because of their chemical resistance and physiological safety. Traditionally, composite components made of elastomer/fabric/PTFE have been used. However, due to the technical risks and associated uncertainties, the trend is shifting toward all-plastic diaphragms, and more recently, those made
Online Seminar with Sealing Expert Stefan Bock Rubber protective bellows are widely used in industry. Bellows made of polytetrafluoroethylene are food-grade and resistant to virtually all chemical attacks. However, special design and manufacturing expertise is required to ensure they meet the performance standards demanded, for example, in the beverage industry. Here you’ll find a “live
Online Seminar with Sealing Expert Stefan Bock Ultra-high-molecular-weight polyethylene is already widely used as a glide surface for skis and snowboards. The material has a low coefficient of friction, is food-safe, and is relatively inexpensive. Compared to polytetrafluoroethylene (Teflon®), it is stiffer and more abrasion-resistant. Nevertheless, UHMW-PE still plays a minor role in sealing technology.
Online Seminar with Sealing Expert Stefan Bock Have you always wanted to know when it’s appropriate to use custom PTFE solutions to solve problems that standard seals can’t handle? How can you prevent Teflon® from “creeping”? Here you’ll find a “live recording” of my first webinar from April 8, 2021. I would really appreciate your
Online Seminar with Sealing Expert Stefan Bock The jacket ring (also known as Stepseal®, Glydring®, rotary slide ring, or stepped ring) is an inexpensive sealing element that virtually EVERY supplier of standard designs carries in its catalog. Due to the simple design of the installation space and the manufacturers’ promises, this piston/rod seal is widely
Online Seminar with Sealing Expert Stefan Bock Hydrogen, as an alternative energy storage medium, is expected to help reduce dependence on fossil fuels and increase the use of renewable energy sources. Because H2 is a volatile molecule, it is typically stored at low temperatures. This places enormous demands on technical equipment in terms of leak
Online-Seminar with sealing expert Stefan Bock PFAS (Per- and polyfluoroalkyl substances) are currently a focus of attention for the European Commission. Restrictions on their production and use are being considered. Fluoroplastics, particularly PTFE, also belong by definition to this group of chemical compounds. These materials have thus far been the material of choice for specialty
