Multilayer Insulation (MLI)

As one stop provider HPS delivers tailor-made multilayer-insulations (MLI) of all sizes and any degree of complexity: thermal design, definition of layer architecture, CAD-design, cutting, edge-finishing, grounding, characterization of performance and acceptance testing.

In addition, HPS-teams from Germany are available day or night to integrate the finished blankets to the flight hardware: efficiency, flexibility and speed “on demand”.

Engineering as well as management, system-engineering and final integration onto the flight hardware is offered by HPS Germany whereas the production is performed by HPS´s former daughter company FHP-Portugal. This is an advantage also when the question of georeturn plays a significant role in the whole project setup. With its perfect combination of engineeringresources and on the basis of highly modern cleanroom manufacturing capacities MLI made by HPS have conquered a steady growing market share.
