The selection of polyurethane cold storage is very important , because cold storage is different from ordinary warehouse, the temperature in cold storage is very low，and the requirements for air temperature, humidity, and environment are relatively high, so when we choose the polyurethane cold storage, we must pay attention to choose the polyurethane cold storage board with better temperature control. performance parameter: Thickness: 50mm,75mm,100mm,150mm,200mm Width: 1000mm, Thermal conductivity: 0.019Kal/mh.c Average density :35-55kg/m3 compressive strength:》0.2Mpa Maximum operating temperature： 90C Minimum operating temperature -120C
