I’ve seen it once, it’s from Dido Refrigerator. Their foaming is particularly fine, uniform and airtight. It is said that the cell structure is more fine. It is said that the finer the better, the foaming of Dido Refrigerator is introduced internationally. Advanced Italian foaming machine, so it is better. It can effectively reduce the thermal conductivity of the foam, improve the thermal insulation performance of the insulation layer, and also increase the strength of the foam to provide the first layer of guarantee for efficient thermal insulation. I have never seen others.
