Kunststoffe international, An Impact Way beyond its Small Market Share
...turers of fluoroplastics are therefore working on improving the sustainability of their products. For example, AGC Chemicals, the U. S. chemical company Chemours and the Bavarian plastic manufacturer Dyneon stopped using perfluorooctanoic acid (PFOA) as a wetting agent in the emulsion polymerization of fluoropolymers years ago as part of a voluntary undertaking. PFOA is very long-lasting and bioaccumulative, meaning that it can become concentrated in the bodies of animals and humans. It has come...
Kunststoffe international, 2005-11-21, Driving the Automotive Industry: Engineering Elastomers
Trend Report Crosslinking Plastics Engineering Elastomers Driving the Automotive Industry. Within the elastomer-manufacturing industry, there is increasing concentration and focus on product groups. Regardless of this, the trend towards relocating production of standard products within the expanded European Union continues to advance. In the future, China and India will also increasingly emerge both as markets and production locations for engineering elastomer products. Werner P. Lauhus The Eu...

Fluor-Rubbers (FPM, TFE/P): Standard products in this elastomer class (Viton, DDE; Dyneon, Dyneon LLC; Tecnoflon, Solvay Ausimont) have high temperature and chemical resistance and good sealing effect at relatively high temperatures (Fig.8), though poor base resistance. They are being continually improved. The new Viton product range GLT-S has an improved polymer architecture, which leads to a much-improved processability with improved ...

Besides improved flowability and demoulding behaviour, a key focal point in fluoroelastomer development is low-temperature performance. The Dyneon grade LTFE 6400X (Dyneon) achieves a temperature retraction value (TR10) of –40°C coupled with good damping properties. This fuel- and lubricant-resistant material is used for injection valve ‘O’ rings, quick-release couplings and radial shaft seals in various sectors,...

Dyneon, St. Paul/Minnesota, is showing two new fluoropolymer processing-aid concentrates that are designed for use at very low levels to cut cost. FX 0914 X and FX 5922 X are the latest additions to the company’s Dynamar family of polymer processing aids (PPAs) that reportedly reduce cycle times, eliminate m...

Good results have been obtained when a fluoropolymer (grade: Dynamar, manufacturer: Dyneon) is incorporated in the melt. Added in small quantities, it lowers the extrusion pressure after a relatively short time and creates a smooth, homogeneous surface again. Such fluoropolymers are already being used in certain processes, for exampl...

The processing aid used was Dynamar FX 5920 A (manufacturer: Dyneon). This was dissolved at a concentration of 0.5% in tetrahydrofuran (THF). The different HALS stabilisers were also dissolved at a concentration of 0.5% in THF in the presence of 0.5% PPA. The test specimens were placed in the different solutions and l...

Until recently the only PPA on the market for use in processing PE were fluorinated products (e.g. Viton from DuPont-Dow Elastomers, Dynamar from Dyneon and Kynar from Arkema). These processing aids achieve processing improvements and better-quality end products. Because of their advantages, fluorinated PPA are used, despite their high price, in the production of blown films, cast films and shee...
