...produced from these fibres. Germany followed soon afterwards with “Perlon stockings” made from polyamide 6. Large-scale polymerisation of PVC commenced at Bitterfeld/Germany. Roy. J. Plunkett (USA) at DuPont discovered – again somewhat by chance – the first fluoroplastic, polytetrafluoroethylene (Teflon). The outbreak of the Second World War in 1939 marked the start of a dark chapter in German history. During the war years up to 1945, there were reports, especially from the UK, of new plastics b...

...er that people give when asked what achievement from the early days of space flight – and the billions of dollars spent on it – benefits our lives today. Apart from the fact that this answer is wrong (after the discovery of PTFE in 1938 by Roy Plunkett, Louis Hartmann developed the first Teflon frying pan back in 1954), this example shows that it often takes innovations a long time to gain broad acceptance in everyday life. And even today, 48 years later, work on improving the Teflon frying pan ...

...sing machines cannot be simulated. Wear studies are therefore carried out on model test systems. Conventional methods are often time consuming and costly. Two innovative, realistic test apparatuses now permit more precise and time-optimised studies. Roy T. Fox Michael Rudschuck Wear testing methods extend from industrial trials on test rigs with original parts to testing on model systems. Field tests are unfeasible for systematic gathering of knowledge about fundamental wear because they are exc...
