Stable material at high temperature

High temperature tests

This week, a couple of severe misuse tests have been performed. Very interesting were the high temperature tests of  a standard PowerFilm element. Even at temperatures between 200°C and 220°C the element stayed 100% stable and was not damaged. To prevent the ground – on which the element was placed on –  from being damaged, we used some insulation material to place the heating surface on. Because of the thinness of the element it is not always 100% connected to the ground and therefore pillows of air are locally trapped between the PowerFilm and the ground. As air is a very good insulator, the areas of the heating element under which air is located, get warmer than areas which are perfectly fitted to the ground. At the demonstrated heating performance this effect leads to locally different temperatures, which can be seen in the picture below.
