... They cannot therefore be processed without the addition of polymer processing aids (PPA). 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 sheets as well ...

...ity, and it also has very high flame retardance. On top of this, it is relatively easy to extrude. Using a special foaming process, the firm Zotefoams plc., Croydon/UK, has now succeeded for the first time in producing expanded parts of PVDF (grade: Kynar, manufacturer: Arkema). In this process, extruded sheets of PVDF are exposed to very high pressures at elevated temperature to saturate the material with nitrogen. In a second stage, the sheets expand by being heated in autoclaves under control...

...imize the non-stick characteristics of kitchenware. PTFE Is always the Starting Material Polytetrafluoroethylene (PTFE) is the starting material for many other fluoropolymers hiding behind the wellknown brand names Teflon (supplier: DuPont), Kynar (supplier: Arkema), Halar (supplier: Solvay) and Dyneon (supplier: Dyneon/3M). PTFE already exhibits the basic characteristic properties such as good tribological features as well as high chemical and thermal resistance. It cannot, however, be injectio...

...ector was first achieved by polyvinylidene fluoride. It was first synthesized in 1944 by Du Pont and introduced in 1961 by the Pennwalt Corp. under the name Kynar. In Europe, PVDF first became known at the end of the 1960s through imports. Solvay & Cie SA, Brussels, Belgium, took up development of PVDF in 1970 and launched its product in 1972/73 under the designation Sole. The commercial products Forefront from PC Urine Cullman and Dilfer 2000 from Dynamite Nobel, Troisdorf, Germany, followe...
