Sandwich Panels, Aluminum and Thermoplastics honeycombs and Foams
POLISTEP is a lightweight sandwich panel with a core in polypropylene with glass fibre reinforced with epoxy resin.
This panel offers unique characteristics since it combines lightweight with high mechanical properties. The application of this panels for example permits huge savings as far as weight and thickness of the slabs of natural stones, such as marbles and granite and mosaics are concerned. In this way, also the costs of these materials can be reduced.
