Dyneon at the Achema: new compounds, innovative 3D printing and resistant FFKM - Leap in performance with new generation of compounds

New Dyneon compound for seals
(PresseBox) ( Neuss, )
At the Achema trade show, Hall 9.0, Booth E36, Dyneon is presenting a new compound that strengthens the frictional connection between the polymer matrix and the filler to a degree that has never been possible before. Components manufactured with this new generation of compounds attain significantly improved mechanical properties. In addition, the company will be demonstrating new possibilities for 3D printing with PTFE and the Up-Cycling of fully fluorinated polymers in Burgkirchen. Another highlight is a Perfluoroelastomer with a well-balanced performance ratio between thermal and chemical resistance.

Dyneon has developed a new generation of compounds that achieves a considerably tighter connection of the 3M Dyneon TFM Modified PTFE with the carbon fiber filler. Comparison measurements show that the first compound from the new generation, 3M Dyneon TFM Modified PTFE Compound PDR 015/310, increases the tensile strength over a wide elongation range. The pronounced yield point gives the material additional safety reserves over the entire usage temperature range from -50 °C to +290 °C. PDR 015/310 also achieves top marks for deformation under compressive loads. With the same quantity of filler, the high-performance material reduces permanent deformations by almost one third. Not only that, the new compound stood out in the comparisons with very high abrasion resistance. 

3D printing for prototypes and small series
Dyneon continues to advance the 3D printing with the technology developed by 3M for the additive manufacturing of PTFE printed parts. The additive process enables the fast and cost-effective manufacturing of usable prototypes and very small series with very complex geometries. Dyneon validates this manufacturing on conventional 3D printers. Manufacturers can thus accelerate the development times for new products or the manufacturing of rarely required spare parts and complex geometries can be printed.

Up-Cycling on a pilot scale
With the Up-Cycling of fully fluorinated polymers at its Burgkirchen works, Dyneon is closing the fluoropolymer recycling loop and in doing so is making an important contribution to the sustainable use of these materials. In a pyrolysis process, up to 95 percent of the perfluorinated polymers are broken down into monomers that can be used in production for the manufacturing of new high-performance materials. Dyneon processes both its own fluoropolymer waste and quantities delivered by third parties in the Up-Cycling plant.

ChemShield – an all-round solution for the chemical industry
Dyneon has developed PFE 7502BZ ChemShield with the goal of satisfying the industry's demands for a material that combines the advantages of the outstanding chemical resistance of a peroxidic cross-linking FFKM with an excellent performance at high operating temperatures in just one product. Only in this way the service life, service intervals and reliability of sealing solutions can be optimised.

The outstanding compression set resistance of this FFKM type and its physical properties profile make it ideally suited for use in solvents, acids, alkalis, amines, water and steam. Furthermore, PFE 7502BZ ChemShield is compliant with the FDA and USP VI standards. This is crucial for its use in the pharmaceutical industry.
