PU/PUR/PIR cold storage sandwich panels are used for the construction of cold storages. The sandwich panel consists of these materials sandwiched between two layers of metal plates, which can effectively keep the cold storage insulated and ensure the quality of items inside the cold storage.
PU (polyurethane) is a multi - functional polymer material with good thermal insulation performance, mechanical properties, etc.
PUR (polyurea) performs excellently in thermal insulation, waterproofing and other aspects, and its molecular structure gives it relatively good stability.
PIR (polyisocyanurate) is a high - performance thermal insulation material. Its thermal insulation effect is better than that of ordinary polyurethane, and it is especially suitable for low - temperature environments such as cold storages with high requirements for temperature control.
The cold storage sandwich panels made of these materials are mainly used for the construction of cold storages. The sandwich panel structure sandwiches the thermal insulation material between two layers of metal plates (such as PPGI/PPGL/ stainless steel, etc.). This structure enables the cold storage to have good thermal insulation performance, which can effectively reduce the heat transfer from the outside to the inside of the cold storage, thereby reducing the energy consumption of the refrigeration equipment in the cold storage and ensuring the stability of the low - temperature environment in the cold storage, which is conducive to the preservation of freshness and quality of items such as food and medicine that need to be stored at low temperatures.

The most important aspect of PU/PUR/PIR cold storage sandwich panels is their excellent thermal insulation performance.
In food cold - storages, they can precisely control the temperature and ensure the freshness of food. When used in pharmaceutical cold - storages, they maintain a stable low temperature and ensure the quality of medicines. In the transit warehouses of the logistics cold - chain, they can effectively insulate heat and reduce the energy consumption of refrigeration. For cold - storages storing items such as mushrooms, flowers, and electronic components that require specific temperature and humidity environments, their good properties such as thermal insulation, waterproof, and moisture - proof can also meet the requirements.
