Multilayer Insulation (MLI)

As one stop provider HPS manufactures and delivers tailor-made multilayer-insulations 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 and Portugal are available day or night to integrate the finished blankets to the flight hardware: Efficiency, flexibility and speed on demand.

Design, analysis, and development tests as well as managament and system-engineering are equally available from Portugal and Germany at customer´s choice. This is an advantage also when the question of georeturn plays a significant role in the whole project setup. With its perfect combination of Portugese and German resources and on the basis of its own highly modern cleanroom manufacturing capacities in Portugal MLI made by HPS have conquered a steady growing market share, so that the number of technicians and engineers in Portugal only has doubled over the last three years.
