The main materials of cold storage panels include:

 

‌1. Polyurethane (PU): It has good thermal insulation and strong support, good durability and is not easy to absorb water. It is suitable for insulation in various irregular areas.

 

2. Polystyrene (EPS/XPS): It has the advantages of light weight, good thermal insulation, and low temperature resistance. It is usually used for floor insulation in freezers.

 

‌3. Rock wool board: Made of natural minerals such as basalt, it has the properties of thermal insulation, noise reduction, good fire resistance, and is suitable for high temperature environments.

 

‌4. Glass wool board: Made of glass fiber, it has low thermal conductivity, waterproof, anti-corrosion, mildew-free, insect-free, and non-flammable. It is suitable for a wider temperature range.

 

‌5. Rubber-plastic insulation material: It is a mixture of rubber and plastic. It has good moisture-proof and mildew-proof, flame-retardant and fire-proof, sound-proof and vibration-proof properties. It is suitable for quick-freezing cold storage with slightly lower requirements for fire resistance.
