Due to increasing requirements, however, alternative materials such as PPS and PPA are becoming increasingly interesting for components. This is illustrated by the example of a coolant distribution pipe for Audi and VW vehicles. Note de contenu : - Which PPA should it be ? - 1.5 million components made of PA9T - Fig. 1 : Since the two-piece coolant distribution pipe was to be joined by rotation welding, PPS was out of the question as a material - Fig. 2 : Material benchmark measured with ISO A1 test bars in 50 % coolant and 50 % water: the PPA and PPS materials investigated have significantly higher long-term stability than the otherwise common PA66 - Fig. 3 : The coolant distribution pipe made of PA9T is now used by Audi as well as VW, Skoda and Seat - Table 1 : Overview of the polymer types investigated En ligne : https://drive.google.com/file/d/1adPks8e74bd8nJ-jDyM4qkA5EKMW7t4m/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=37211 [article]
