Polyurethane cold storage panels are the core insulation materials of cold chain systems. Their outstanding performance mainly stems from their unique material structure and efficient core materials. It usually has lightweight polyurethane as the inner material, and the outer part is composed of materials such as color steel plates or stainless steel plates. This composite structure can effectively suppress heat transfer.
The core advantage of polyurethane cold storage panels lies in their extremely high closed-cell rate (usually over 90%). These numerous independent and closed tiny pores inside are isolated from each other, making the conduction of heat within them extremely difficult. Its thermal conductivity is extremely low. According to the data, when the density of rigid polyurethane is 35 to 40kg/m³, the thermal conductivity can be as low as 0.018 to 0.023W/(m·K), which is approximately half that of EPS. This means that under the same insulation requirements, the thickness of the building's exterior envelope can be reduced, thereby increasing the indoor usable area.
In addition, this closed-cell structure also endows the board with excellent moisture-proof and water-proof performance. Due to the closed pores, moisture is difficult to enter, and the thermal conductivity will not increase due to moisture absorption. The wall will not seep water either, and it can maintain stable insulation performance for a long time. Polyurethane cold storage panels also have excellent fire resistance. After adding flame retardants, they are self-extinguishing materials that are difficult to burn. Their softening point can reach above 250 degrees Celsius, and they will only decompose at higher temperatures, effectively preventing the spread of fire.
For Coowin Holding, the polyurethane cold storage panels we produce inherit these natural advantages. Through carefully selected raw materials, precise foaming processes and strict quality control, we ensure that each panel has stable and reliable insulation performance, helping your cold storage significantly reduce energy consumption and electricity expenses.
