In the aquatic cold chain industry, the selection of cold storage panels is crucial as it directly affects the freshness and storage cycle of aquatic products. Currently, with the growth of global aquatic trade, cold storage panels that combine insulation, durability, and strong moisture resistance have become a focus of attention.

The long-term high humidity and frequent temperature changes in aquatic cold storage make it easy for water vapor to condense. If the moisture resistance of ordinary cold storage panels is insufficient, problems such as frosting, deformation, and insulation failure may occur, increasing energy consumption and causing deterioration of aquatic products. Therefore, moisture resistance has become the primary criterion for selection.
The mainstream materials for cold storage panels in the market include polyurethane sandwich panels, polystyrene sandwich panels (EPS), and extruded polystyrene panels (XPS). Polyurethane sandwich panels have outstanding comprehensive performance, high closed cell rate, and low water absorption rate. By adding moisture-proof agents and optimizing panel processes, the moisture-proof properties are enhanced. When combined with colored steel plates or stainless steel plates, they can resist water vapor, salt erosion, and extend the service life of cold storage.
Polystyrene sandwich panels have low cost but weak moisture resistance, and are prone to expansion and cracking in long-term high humidity environments. They are suitable for low-temperature storage with low moisture requirements and are not suitable for aquaculture cold storage. Extruded polystyrene board has better moisture resistance than EPS, but its insulation performance is inferior to polyurethane. It is often used as an auxiliary insulation material for aquatic cold storage.
Professionals say that when choosing seafood cold storage panels, in addition to considering the moisture resistance indicators of the material, attention should also be paid to the splicing process. Panels with tongue and groove splicing or sealed with sealing strips can reduce the infiltration of moisture into the gaps and improve the overall moisture resistance effect. In addition, the thickness and material of the panel should be adapted to the storage temperature and type of aquatic products. For example, for ultra-low temperature cold storage, thicker polyurethane core materials and low-temperature resistant panels are required.
With the improvement of cold chain standards in the aquaculture industry and continuous innovation by manufacturers, some "moisture-proof enhanced polyurethane cold storage panels" have improved their formula and coating technology, with a water absorption rate of ≤ 0.5%, UV resistance, acid and alkali resistance, and are suitable for coastal areas and large aquaculture processing enterprises.
When selecting cold storage panels for aquatic enterprises, they can prioritize products that have passed the national cold storage insulation material testing standards based on their own storage scale, temperature requirements, and geographical environment. They should also pay attention to the installation and after-sales service provided by the manufacturer to ensure the long-term stable operation of the cold storage and reduce the loss rate of aquatic products.
