What is PU sandwich?

   PU sandwich panels, also known as the metal surface energy saving PU sandwich panels, metal surfaces polyurethane composite panels, polyurethane foam insulation board, polyurethane composite panels, polyurethane panels, PU board, polyurethane sandwich panels popular argument.

   When the bonding strength polyurethane sandwich panels is not less than 0.09MPa, sandwich burning properties of B1 level, flexural capacity sandwich deflection of Lo / 200 (Lo is the distance between bearings), sandwich flexural carrying capacity of not less than 0.5Kn / m2. Effective width of the sheet is usually 1000mm, length can be customized.

   This product has the following characteristics:

   1) thermal conductivity, low thermal conductivity PU sandwich composite panels, good insulation properties, is the best insulation material.

   2) plate appearance, easy installation

   3) Good fireproof PU sandwich panels

   4) non-toxic, odorless PU sandwich panels

   5) Use a wide temperature range

   6) Waterproof, moisture

   PU sandwich panel appearance, the overall effect is good, it sets bearing, heat, fire, water in one, and without re-decoration, quick and easy installation, short construction period, the overall efficiency is good, with a good price advantage, is a versatile, highly efficient energy-saving potential in the building envelope materials, but also the Ministry of Construction to promote energy conservation and promotion of a new sheet.
