Polyurethane foam sandwich panel is fit for the projects whichhave serious require of keeping warm. Polyurethane core material isconsidered to the best material in keeping warm and thermalinsulation.
The Polyurethane block material become steady after it froth, thencombining with metal plates. The characteristics of this techniqueare: the polyurethane froth, after this chemical reaction isstable, we cut the polyurethane into pieces which with differentthickness. The polyurethane sheet material has stable physicalperformance, it can combine with prepainted gaivanized steelsheets, the surface is smooth and the whole performance isexcellent.
The characteristics of polyurethane foam sandwich panel:
Polyurethane foam sandwich panel(the abbreviation of Polyurethaneis PU sandwich panel)have characteristics of high load intensity,small water-absorptivity , and the stability in either lowtemperature or the high temperature is good, the service life islong, thermal insulation performance is outstanding and so on.
Good supporting, heat resistant, sound-insulated, sound absorption,light quality, non-toxic, odorless, green environmentalprotection.
Polyurethane foam sandwich panel can cementation with the steelplates, the cements, the fiberboards, the bricks and many kinds ofmaterials very strongly, in usual situation, it would not fall offand still strengthen its thermal insulation and waterproofingeffects.
The unique produce foaming craft made the products have exquisiteand even abscesses, the Thermal conductivity is low, the sizestability is good, is very suitable for both of the low pressureand the high pressure construction.
Polyurethane foam plastic,s thermal stability is quite good, whenthe temperature is lower than 120 C, the volume and the intensityhave no obvious change, its Thermal conductivity is small, when thedensity is 0.03kg/m3, the heat conductivity is only63J(m.h.k)(15cal/m.h.k).
It can be widely used as structural materials and heatproofmaterials in petroleum industry, chemical industry, construction ,packing, refrigeration, military industry, space industry,aviation, transportation and industrial model design and othervarious aspects .
