Polyurethane cold storage panels are made with lightweight polyurethane as the core material. The benefits of polyurethane are its excellent thermal insulation properties. The exterior of the polyurethane cold storage panels is composed of SII, colored steel plates with PVC, and stainless steel components. This design effectively prevents temperature transmission due to significant temperature differences inside and outside the panels, making the cold storage more energy-efficient and improving its operational efficiency. The cold storage panels feature corrosion resistance, aging resistance, flame retardancy, non-toxicity, lightweight affordability, durability, safety, reliability, attractive appearance, ease of operation, long service life, and hygiene.
