What are the advantages of polyurethane cold storage panel?

In the cold storage project, more than 90% of the cold storage installations are made of polyurethane materials as the cold storage board. So why do so many people choose polyurethane cold storage board? Let me introduce the advantages and characteristics of this material in detail below.

Polyurethane cold storage board has a light-weight polyurethane cold storage internal material. Polyurethane has good benefits. It is composed of external SII, PVC color steel plate and stainless steel plate. This advantage is to prevent the cold storage board from being caused by the temperature difference between inside and outside, so that more energy-saving cold storage can be improved. Work efficiency.

Rigid polyurethane has low thermal conductivity and good thermal performance. Polyurethane cold storage board is moisture-proof and waterproof. With a closed cell ratio of more than 90%, rigid polyurethane is a water-repellent material, which will not increase the thermal conductivity due to moisture absorption, and the wall will not leak.

Polyurethane cold storage board also has the characteristics of flame retardant and high temperature resistance. After adding flame retardant, polyurethane is a kind of material that is difficult to burn and self-extinguishing. Its softening point can reach 250 degrees Celsius or more. Only when the temperature is extremely high will decomposition occur. In addition, it will also form a layer of ash on the surface of the foam when it burns. This layer of ash can help isolate the foam below and effectively prevent the spread of fire. In addition, polyurethane does not produce harmful gases at high temperatures.

As the polyurethane board has excellent thermal insulation performance, under the same thermal insulation conditions, the thickness of the building envelope can be reduced, thereby increasing the indoor use area.

In addition, the polyurethane cold storage board also has the characteristics of strong deformation resistance, not easy to crack, stability, and strong safety. The stability of the pore structure of the polyurethane material is basically a closed cell structure, which not only has excellent heat preservation performance and freeze-thaw resistance, but also has good sound absorption properties. The average life of rigid foam polyurethane insulation structure can reach more than 30 years under normal use and maintenance.
