VIP used for freezers, ultra cold facitities, etc.

Thermal conductivity      ≤0.***5（W/ m · K）

Overall density           **0（kg/m3）

Compressive strength      0.***0.*5( M pa )

By using VIP in refrigerator, the energy can be saved at least *0%**0%; by taking the VIP as insulating material, besides the economy reason, it's also of light weight, thin wall, it's significant to apply it in refrigerators and freezers' door                      

When taking PU or PF as insulating material, the heat reserving period is only **2 days; after applying VIP, the insulating period can be prolonged to **5 days. Therefore, the transportation cost can be significantly reduced by land transportation instead of air transportation

Put the same items in two cold-storage boxes , the usage of refrigerant in the box with VIP is evidently less while its tempering stage holding time is considerably prolonged.
