PROPERTIES
  • High rigidity combined with a very low overall weight.
  • Excellent dimensional stability, also in terms of flatness over time.
  • Very good compressive strength (due to aluminium honeycomb).
  • Excellent resistance to peeling.
  • Ease of machining with manual or CNC equipment suitable for woodworking.
  • Wide operating temperature range.
  • Surface particularly suitable for gluing additional finishes.
     
    FIELDS OF APPLICATION
    The RAWCELL® Wood - OKU panel is used in the field of interior fittings, transportation (motor homes) and design (furniture, doors, wings); it is often used as a cladding material (walls, ceilings).
    STORAGE
    The RAWCELL® Wood - OKU 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.
