Product Description:

Polyurethane sandwich board is an innovative type of building material that offers several advantages over conventional options. This board comprises of two layers of metal sheets (usually galvanized steel plate, color steel plate, etc.) with a polyurethane hard foam core material in the middle. This unique structure creates a board that possesses the strength of metal sheets and the exceptional performance of polyurethane core material.

Polyurethane rigid foam core material is produced using a mixture of isocyanate and polyol under specific conditions. The result is a uniform and fine closed cell structure inside the foam core material, which offers several benefits over other types of building materials. The production process for sandwich panels is advanced and involves tightly combining each layer to form a firm and robust panel, which is ideal for construction applications.

Features:

Our product boasts several key characteristics that make it an excellent choice for building insulation.

Compared to traditional insulation materials, our polyurethane has an extremely low thermal conductivity of between 0.018-0.024 W/(m · K). This is due to the closed cell structure of polyurethane, which effectively reduces heat conduction, convection, and radiation. As a result, your building can be kept warm in the winter and cool in the summer, which greatly reduces your energy consumption and contributes to energy-saving and emission reduction.

By adding appropriate flame retardants, our polyurethane sandwich panels can achieve different fire ratings, such as B1 (flame retardant) or even A2 (non-flammable). In case of a fire, our panels can effectively delay the spread of flames, reduce heat release and smoke generation, gain valuable time for personnel evacuation and fire rescue, and improve the fire safety of the building.

Polyurethane is a hydrophobic material, and its closed-cell structure also prevents water penetration. When combined with the outer metal sheet, our sandwich board can effectively resist the erosion of rain, snow, and humid air. This ensures the long-term stability of the thermal insulation system, avoiding problems such as thermal insulation performance decline, mold, rot, and other problems caused by moisture.

The upper and lower layers of sheet metal provide enough strength for our sandwich board to withstand large external forces, such as wind loads, snow loads, and the weight of personnel and equipment. In addition, the polyurethane core material gives the sandwich board a certain elasticity and toughness. This helps ensure that it does not easily deform or sustain damage when subjected to external forces, ensuring the stability of the building structure.

Our polyurethane sandwich board has a good barrier effect on the transmission of sound, making it an excellent choice for reducing noise pollution. It can effectively reduce the interference of external noise on the indoor environment, creating a quiet and comfortable living and working space for people. The sound insulation performance of the thick and moderate density sandwich board is better, and the degree of sound insulation depends on the thickness and density of the sandwich board.

Our polyurethane sandwich panels come in standardized sizes and specifications, are relatively light in weight, and are easy to handle and install. At the construction site, a variety of installation methods can be used, such as splicing, anchoring, etc. The installation process is simple and fast, which can effectively shorten the construction period and reduce the construction cost.

The outer metal sheet can have a variety of colors and surface treatment methods, such as galvanized, color coating, etc. This means that our sandwich board can be aesthetically pleasing and match the architectural style that you require. The metal sheet and polyurethane core have excellent durability, allowing them to resist the effects of natural factors like ultraviolet light, chemical substances, and temperature changes. This extends the service life of our sandwich board.

Applications:

Polyurethane sandwich panels are widely used in various fields, including industrial building, commercial building, residential building, cold chain logistics, and agricultural facilities.

Polyurethane sandwich panels are commonly used in industrial plants, warehouses, logistics centers, and other buildings. This material provides stable temperature and humidity conditions for the production environment, reduces heat exchange, minimizes heating and cooling costs, and meets the requirements of industrial production for building strength and fire performance. For instance, in warehouses and logistics centres, polyurethane sandwich panels prevent changes in temperature and humidity, and ensure the quality of the stored goods.

Polyurethane sandwich panels are highly applicable in shopping malls, supermarkets, hotels, office buildings, and other commercial places. In shopping malls and supermarkets, polyurethane sandwich panels help to maintain a comfortable indoor shopping environment while reducing energy consumption. In hotels and office buildings, polyurethane sandwich panels provide efficient sound insulation, thermal insulation, and fire protection performance, creating a high-quality environment for customers and office workers.

Polyurethane sandwich panels are commonly used in the external wall and roof insulation, as well as indoor partitions of residential buildings. In external wall insulation, polyurethane sandwich panels significantly improve the thermal insulation performance of residential buildings and reduce energy consumption. In roof insulation, polyurethane sandwich panels effectively protect the roof structure and prolong the service life of the waterproof layer. When used as indoor partitions, polyurethane sandwich panels create a beautiful look and provide a certain sound insulation effect.

The construction of cold storage is an essential application field of polyurethane sandwich panels. The excellent thermal insulation performance of polyurethane sandwich panels ensures the temperature stability in the cold storage, reduces the energy consumption of refrigeration equipment, and guarantees the storage quality of refrigerated and frozen goods. Moreover, the moisture-proof and antibacterial properties of polyurethane sandwich panels are conducive to maintaining a sanitary environment in the cold storage.

Polyurethane sandwich panels are commonly used in agricultural greenhouses, agricultural products warehouses, and other facilities. In greenhouses, polyurethane sandwich panels adjust the indoor temperature, humidity, and light, creating a suitable environment for crop growth. In agricultural products warehouses, polyurethane sandwich panels maintain freshness and extend the storage period of the agricultural products.

Packing and Shipping:

The PU sandwich panels will be packaged in bundles with protective plastic sheets and steel straps. The bundles will be securely stacked onto wooden pallets for safe transportation. Each bundle will be labeled with the product name, size, and quantity for easy identification.

Shipping:

The PU sandwich panels will be shipped via truck or sea freight, depending on the destination. The panels will be loaded onto flatbed trucks or shipping containers and secured with steel straps to prevent damage during transit. Our logistics team will work with the shipping company to ensure timely delivery and safe handling of the products.
