PU Board Aluminum Core structure

PU Board Aluminum is an innovative composite board. Its core is polyurethane (PU) – the closed-cell structure delivers excellent thermal insulation, sound insulation and waterproofing. The outer layer is aluminum foil or aluminum alloy, which leverages aluminum's light weight (density 2.7g/cm³), corrosion resistance and easy processability to protect the PU core.

Type: Aluminum Foil-faced Polyurethane Panel: A layer of aluminum foil (common thickness 60-80μm) is bonded to the polyurethane board surface, e.g., the widely used 80μm aluminum foil-faced products in the industry. With over 90% reflectivity, the aluminum foil layer strengthens thermal radiation barrier, boosting overall thermal insulation efficiency by 15%-20%. It also enhances surface scratch and moisture resistance, ideal for cold storage, pipeline insulation and similar scenarios.

The Advantages Of PU Board Aluminum: Comprehensive performance breakthroughs

Ultimate heat insulation: The polyurethane core has a thermal conductivity as low as 0.022W/(m·K). Combined with the heat reflection of the aluminum layer, its heat insulation performance is more than 40% better than traditional rock wool boards, significantly reducing building air - conditioning energy consumption.

Structural stability: With the reinforcement of aluminum, the flexural strength reaches 15MPa. The dimensional change rate is less than 0.3% in the environment of -40℃ to 80℃, and it can bear a uniform load of 1.5kN/m² without deformation.

Comprehensive protection: The aluminum layer forms a barrier, with a water absorption rate of less than 1% and a moisture - proof level of IPX7. The polyurethane core with flame retardants can reach the B1 fire rating, and the aluminum layer can also slow down the spread of flames.

Long - term durability: After anodizing or fluorocarbon spraying, the aluminum layer has an outdoor service life of more than 25 years, with excellent surface color retention and no need for frequent maintenance.

Application fields: Cross-industry preferred choice

Building systems: Used as wall insulation layers and core materials for roof systems, applicable to industrial plants (reducing workshop temperature difference by 5-8℃), commercial complexes (reducing air conditioning load by 20%) and low-temperature storage facilities.

Cold chain transportation: After refrigerated trucks adopt this board, the temperature fluctuation inside the box can be controlled within ±1℃, and energy consumption is reduced by 25%, making it suitable for fresh food logistics and pharmaceutical cold chain.

Special fields: Relying on the advantage of specific strength (strength/weight ratio), it is used for insulation in bullet trains, meeting the requirements of lightweight and sound insulation.

"PU Board Aluminum" reshapes the performance standards of composite boards through material innovation, and becomes the preferred product for modern construction and industrial fields in pursuit of efficient, durable and environmentally friendly solutions.
