Lightweight sandwich wall panel, also known as lightweight composite panel, is made of either light materials or light structures. Its two sides are provided with tenon grooves and joint grooves, and the area density is not more than the standard value (Panel-90: 90kg/m2, Panel-120:110kg/m2 ). It can be used as a prefabricated panel for the non-load-bearing inner partition wall of industrial and civil buildings.

The application of MikaZone™ Cellulose Ether can significantly enhance the machinability of the extruded lightweight sandwich panel, which makes it have higher adhesion strength and lubricity, and improve the wet strength of the mortar and the adhesion of the panel after extrusion.
