Urethane sandwich panel means that the upper and lower layers are metal sheets, and the core material is a thermal insulation material with a certain rigidity, such as rock wool, rigid foam, etc., which are composited on a special automatic production line. , also known as a "sandwich" board.
Main technical indicators to be considered in the selection of polyurethane sandwich panels Main technical indicators to be considered in the selection of metal-faced sandwich panels Main technical indicators to be considered in the selection of metal-faced sandwich panels Index Bonding performance, peeling performance, flexural bearing capacity, thermal conductivity, fire resistance limit, combustion performance.
The bulk density of the polyurethane sandwich panel is 35～40kg/m3 , the thermal conductivity: 0.018-0.023, the thermal conductivity is low, and the thermal performance is good
