A sandwich panel is any structure made of three layers: a low-density core and a thin skin-layer bonded to each side. Sandwich panels are used in applications where a combination of high structural rigidity and low weight is required. SIP is a sandwich structured composite, consisting of an insulating layer of rigid core sandwiched between two layers of structural board, used as a building material. A structural insulated panel, or structural insulating panel, (SIP), is a form of sandwich panel used in the construction industry. The board can be sheet metal, plywood, cement, magnesium oxide board (MgO) or oriented strand board (OSB) and the core either expanded polystyrene foam (EPS), extruded polystyrene foam (XPS), polyisocyanurate foam, polyurethane foam or composite honeycomb (HSC).me
Sandwich panels in India have been showing strong growth mainly in telecom shelters, cold chain and industrial buildings. Hunts man is a leading supplier of polyure thane (PU) chemicals to sandwich panel manufacturers across the world. In this paper, we would like to share our experience gained in Europe for sandwich panel applications. In the Europe, Africa, Middle East (EAME) region, the market for polyure thane- cored sandwich panels has been growing rapidly over the last years and is currently estimated to be 130 million per annum. The majority of these panels are produced on laminators while the discontinuous press technique is mainly used for more specialized panel designs. As a whole entrepreneur can venture in this field will be successful.
