Description of the product

MA4 is a sandwich panel with a cosmetic finish consisting of a thin marble slab (4 mm). It has an aluminium honeycomb core and skins made of glass fibre fabric. It is obtained by gluing a marble finish slab to a panel without finish such as the RAWCELL® Fiber panel. Main fields of application: construction, furniture, shipbuilding, lifts.

PROPERTIES

  • Very high resistance to bending, shear and tensile stress.

  • Excellent resistance to peeling.

  • Excellent dimensional stability, also in terms of flatness over time.

  • Very good compressive strength (due to aluminium honeycomb).

  • Maximum mechanical performance, compared to the high lightness of the panel.

  • Excellent weather resistance.

  • Wide operating temperature range.






FIELDS OF APPLICATION

Typical applications for the LITHOCELL® Natural Stone - MA4 panel include building façades, interior design and lift systems.




STORAGE

The LITHOCELL® Natural Stone - MA4 panel is a product in the “semi-finished products” category and therefore is subject to further processing; we recommend storing the panels horizontally in a closed and dry environment, possibly away from heat sources and to support them along their edges.
