Key Advantages
Superior Thermal Insulation: Features a thermal conductivity of just 0.018–0.024 W/(m·K) and a closed-cell rate of ≥90%. At the same thickness, it offers far better insulation than other core materials, significantly reducing refrigeration energy consumption and minimizing internal temperature fluctuations.
Suitable for Cold Storage Conditions: The closed-cell structure ensures extremely low water absorption, preventing deformation from moisture and cracking during cold retention. It is compatible with a wide operating temperature range (-45°C to 75°C) and maintains insulation performance over long-term use.
Structural and Installation Friendly: With a compressive strength of 150–300 kPa, it can serve as a load-bearing wall component. The tongue-and-groove joint design ensures a tight seal, effectively preventing thermal leakage.
Selection Options for Other Scenarios
Small Cold Storage with Limited Budget: XPS (Extruded Polystyrene) sandwich panels are a suitable choice; they offer excellent moisture resistance and compressive strength, making them ideal for floor insulation.
Cold Storage Areas with Strict Fire Safety Requirements: Polyurethane-edged rock wool sandwich panels are recommended, as they combine Class A fire resistance with effective insulation performance.
