PU Foam Aluminum Panel
It is a high-performance ventilation duct product, which is widely used in HVAC systems. The following is a detailed introduction:
Basic Structure: It is a sandwich structured panel. The core is Polyurethane(PU) foam, which is a closed-cell insulating material. The two outer layers are aluminum sheets or aluminum foils.
Panel Structure: Silver Alu. Foil/ PU Foam/ Silver Alu. Foil
Foam Density: 50kg/CBM
Panel Dimension: 3950mm*1200mm*20mm
Alu. Foil: 60 or 80 Micron (Embossed)
Fire Rating: Class 0 (BS476Part 6&7)
Core attributes and technical advantages of PU Foam Aluminum Panel
Composite structure and process: It adopts a three-layer structure of "aluminum plate + PU foam core + aluminum plate", formed through a hot-melt composite process. There is no solvent evaporation, and the bonding strength is ≥4N/cm, avoiding the risk of delamination. The closed-cell rate of PU foam exceeds 90%.
Key performance parameters: Outstanding thermal insulation and heat preservation performance, with a thermal conductivity that is only half of that of traditional boards, and the insulation effect of the same thickness is 1.5 times that of rock wool boards. The 20mm thick sheet has a sound insulation capacity of 20-40dB, an energy absorption capacity of 8-30J/cm³, and also features shock absorption and buffering functions. It has A fire resistance rating of B2 (upgradable to A), does not soften at 600℃ and does not release any toxic gases.
Practical feature compatibility: The density is only 1/10 of that of solid aluminum plates, significantly reducing the structural load. It can be sawn, drilled and bent, meeting personalized processing requirements, and the installation efficiency is increased by more than 30%. It is non-hygroscopic and resistant to salt spray corrosion.
Highlights of Differentiated Competition of PU Foam Aluminum Panel
Compared with traditional insulation materials: Compared with rock wool boards and EPS boards, PU foam aluminum boards have a lower thermal conductivity, a more lasting insulation effect, and also have the functions of fire resistance, sound insulation and load-bearing, without the need for additional protective layers. Compared with pure PU foam boards, the surface layer of aluminum plates has solved the pain points of easy wear and poor impact resistance, and is applicable in a wider range of scenarios.
Compared with honeycomb aluminum panels: Under the same thermal insulation and soundproofing effect, the cost of PU foam aluminum panels is 15-20% lower, and the processing difficulty is smaller. They can be cut and formed without special equipment. It is lighter in weight (20-30% lighter than honeycomb aluminum panels).
Environmental protection and cost-performance advantages: Water-based foaming agents are used to replace traditional fluorides, with VOC emissions approaching zero, meeting REACH environmental protection standards. Continuous production processes enhance efficiency. It can be 100% recycled and reused, meeting the demands of green production.
Industry application scenarios of PU Foam Aluminum Panel
In the field of building materials: It is used for exterior wall insulation and decorative panels, ceiling sound insulation boards, and the roofs and walls of steel structure factories. It can reduce building energy consumption by more than 30%, while meeting the requirements of sound insulation and fire protection, and is in line with green building standards.
In the field of cold chain logistics: As an insulating body material for cold storage and refrigerated trucks, it performs stably in an environment ranging from -50℃ to 70℃, effectively reducing cold capacity loss, enhancing the efficiency of cold chain transportation, and lowering operating costs.
In the automotive and transportation sectors: It is suitable for interior sound insulation boards of new energy vehicles, lightweight structural components of vehicle bodies, and shock absorption and heat insulation layers of high-speed railways and ships. It can reduce the weight of the vehicle body by 5-8%, helping to increase the driving range and ride comfort.
