BERGHOF Lab autoclave HR-700

The batch process is a discontinuous foaming process showing a good reproducibility due to the exact process controlling. It is mainly qualified for investigations of the foaming behaviour of polymers and polymer systems, however there are also industrial applications. Physical blowing agents as carbon dioxide or nitrogen are commonly used. For foaming polymers via batch-process two different methods can be used, the temperature-induced and the pressure-induced method. The temperature-induced method is a simple and fast tool for first screening experiments of materials, whereby significant effects such as nucleation can be proven.

At the Department of Polymer Engineering, materials can be examined with the lab autoclave on their foaming behavior by using the pressure as well as the temperature-induced method. In this autoclave, the materials can be saturated with the desired blowing agent under pressure and temperature. Subsequently, the samples can be expanded either by pressure drop or in an oil bath from Julabo.
