Polyurethane Aluminum Sheets
Polyurethane (PU) foam pre-filled air duct panels are the preferred solution for air distribution in central air conditioning systems, renowned for their advanced design and energy-efficient performance. As one of the most cutting-edge air duct systems in the world, it combines pre-filled polyurethane foam duct panels without chlorofluorocarbons (CFC) and hydrochlorofluorocarbons (HCFC) with professional accessories and installation tools.

Technical Advantages and Performance Logic of Polyurethane Aluminum Sheets
Thermal Insulation Performance: The PU closed-cell structure blocks heat conduction, and the high reflectivity of the aluminum surface (>90%) further reduces radiant heat transfer. The overall insulation efficiency is improved by 15%–20% compared to traditional materials, meeting the requirements of nearly zero-energy buildings.
Structural Mechanics: The sandwich structure achieves "lightweight + high strength", with the self-weight being only 1/3 of that of steel plates under the same strength, significantly reducing structural loads and transportation and installation costs.
Fire Resistance Upgrade: Through the use of flame retardants and structural optimization, B1-grade products can meet the requirements of most public buildings, while A2-grade products are suitable for higher safety standard scenarios.
Industry Application Value and Economicity of Polyurethane Aluminum Sheets
Building Energy Efficiency: In new construction and renovation projects, an energy saving rate of 65% or higher can be achieved. The material premium can be recovered within 3-5 years, and significant carbon emission reduction can be achieved throughout the entire lifecycle.
Cold Chain Logistics: In an environment of -18℃, a 100mm thick board can be reduced by 20% while still meeting the insulation requirements, thereby reducing the energy consumption for cold storage construction and operation.
Industry and Grain Storage: Moisture-proof, pressure-resistant, and corrosion-resistant, suitable for controlled atmosphere grain storage and harsh industrial environments, extending the lifespan of equipment and materials.
