Do we already need alternatives to PTFE, FKM, and FFKM? Consequences of 3M (Dyneon) Exiting PFAS Production On December 20, 2022, 3M Company, headquartered in St. Paul, Minnesota, announced that the globally operating corporation would phase out the manufacture of PFAS (per- and polyfluoroalkyl substances) by 2025.
We develop and manufacture custom lines made of modified polyethylene. To flexibly connect process connections for liquid media in beverage processing, the food industry in general, the pharmaceutical industry, and the chemical industry, prefabricated PTFE-lined hose assemblies have traditionally been used. A one-piece, thick-walled hose made of ultra-high-molecular-weight polyethylene eliminates the disadvantage that leakage is
With PTFE bellows, it was previously possible to reinforce highly stressed areas with PEEK. It also made sense to use compounds for wrench flats, threads, and guide surfaces. When using PFAS-free bellows made of polyethylene, this is no longer necessary. Due to the strength of the alternative materials Endulfon P1 and P16, one-piece bellows can
A so-called solid radial shaft seal is machined from tube or solid stock and formed to the nominal shaft diameter so that it can also be optimized for low friction. The sealing lips can be designed to face either the same or opposite directions, allowing two media to be separated (e.g., food products from gear
Until now, Teflon® bellows made of virgin PTFE have been the standard. Since this fluoropolymer has come under scrutiny as an environmentally critical material, ultra-high-molecular-weight polyethylene (UHMW-PE) has increasingly gained importance. Components made from this material can likewise be machined and therefore individually customized. PE 1000 offers exceptional flex fatigue resistance. The material is physiologically
For highly loaded components, the base body can be made of metal (stainless steel, aluminum, cast iron, etc.). Using the fluidized-bed coating process, a plastic coating up to 1 mm thick can be applied and subsequently machined. This allows tight tolerances (down to IT7) to be achieved for use as clearance seals or guide surfaces.
An Attempt to Draw Historical Parallels Many of our customers ask us: What does the future hold for PTFE and fluoropolymers? With so many stakeholders, politicians, media organizations, lobbyists, companies, and consumer advocacy groups around the world involved in the discussion and seeking to influence its direction, making a precise prediction is virtually impossible. In
PFAS are per- and polyfluoroalkyl substances, which include fluoropolymers such as PTFE. The decades-long, uncontrolled use of fluorinated compounds has raised significant social and political concerns. The global environmental impacts, including those caused by the careless release of fluorinated surfactants, cannot yet be fully assessed. Everyone who has used PFAS to date should take responsibility

The PFAS-free material with excellent wear resistance UHMW-PE (ultra-high-molecular-weight polyethylene) has a structure that is relatively similar to that of PTFE. Instead of fluorine, the carbon chains are bonded to hydrogen atoms. This significantly alters its range of applications.
