Sandwich panels, with their core characteristics of lightweight, high strength, thermal insulation, sound insulation, modularity, and easy installation, have been widely and innovatively applied in fields such as construction, transportation, industry, and infrastructure due to the flexibility of material combinations. They have become a key material in modern engineering.
1、Exterior walls and roofs
It is suitable for projects such as the reconstruction of old communities. The combination of high-density fiberboard outer layer and polyurethane foam core material can not only reduce the wall load, but also improve the thermal insulation performance and reduce energy consumption; Modular design adapts to the needs of rapid construction and supports sustainable urban renewal.
2、Cold storage and food processing plants
Metal sandwich panels can efficiently insulate and prevent moisture, stabilize low-temperature environments, and ensure the storage safety and quality of temperature sensitive items such as food and medicine.
3、Commercial and Industrial Buildings
The panels used for exterior walls and roofs have excellent fire resistance and corrosion resistance, and can withstand harsh weather and external impacts; Industrial buildings such as factories and warehouses utilize their thermal insulation properties to maintain stable temperature in the production environment, while enhancing structural design flexibility due to their lightweight characteristics.
1、Interior of rail transit vehicles
The high-speed rail carriages use fire-resistant resin surface layer and basa wood core panel, replacing the traditional metal roof, which not only reduces the weight of the vehicle, but also reduces the noise level during tunnel passage from 75 decibels to a comfortable range. The modular design is also easy to maintain quickly.
2、Aerospace components
The components such as the unmanned wing beam are made of fiber-reinforced polyimide thermoplastic structural panels, with a structural efficiency coefficient (stiffness/mass ratio) increased by 3.2 times, significantly enhancing flight performance.
3、RV and transportation equipment
PVC core composite sandwich panels are used for the shell wall panels, floors, and bathroom vertical panels of RVs, integrating lightweight, high-strength, and thermal insulation. The convenient installation method further enhances the durability and functionality of RVs.
1、Modular construction of data center
Composite exterior wall panels combined with flexible connection node technology achieve improved insulation performance and fast and safe assembly. For example, the remote area computing power center project relies on modular panels for rapid deployment, balancing structural strength and durability.
2、Switchgear and electrical equipment
The combination of thin aluminum plate and epoxy laminated board is applied to the valve of PM level switchgear, with high overall strength and good grounding continuity, meeting the pressure resistance requirements; Compact design reduces phase to phase distance, shields magnetic field interference, and improves the current carrying capacity of conductive circuits and equipment reliability.
3、Logistics and Cold Chain Transportation
Metal sandwich panels are used in refrigeration facilities and containers to maintain a stable low-temperature environment. Their moisture resistance effectively prevents moisture damage to goods and ensures the freshness of food and other items during transportation.
1、Architectural Decoration and Curtain Wall
High temperature durability bonding is achieved with polyimide resin, and the glass transition temperature (Tg) of the panel material is ≥ 143 ℃. It combines lightweight, high temperature resistance, and decorative properties, and is suitable for modern architectural aesthetics and structural support needs.
2、Industrial bonding solutions
Henkel customized single/two-component PU adhesive, specially designed for sandwich board bonding, can provide hard or flexible systems, and provide high-end technical support for structural assembly in complex scenarios.
Sandwich panels, with their core advantages of lightweight, high strength, thermal and sound insulation, and modularity, have been deeply integrated into various fields such as building updates, rail transit upgrades, data center construction, and aerospace manufacturing. In the future, with the continuous progress of materials science, its application boundaries will be further expanded, providing efficient and sustainable solutions for more industries.
