1000mm Wide Polyurethane Composite Panel Decorative With B1/B2 Fireproof Grade

Product Description:

Polyurethane sandwich board is a revolutionary building material that is made up of two layers of metal sheet and a polyurethane hard foam core material in the middle. Typically, galvanized steel plate or color steel plate is used for the outer layers. This innovative design provides the polyurethane sandwich board with the superior strength of metal sheet as well as the exceptional performance of the polyurethane core material.

The polyurethane rigid foam core material is created by mixing polyol and isocyanate under specific conditions, which results in a uniform and fine closed cell structure inside. The production process of the sandwich panels is extremely advanced, ensuring that the layers are tightly combined to form a whole. This process produces high-performance panels that are perfect for construction applications.

Features:

One of the main advantages of polyurethane sandwich panels is its excellent thermal insulation performance. Compared to other traditional insulation materials, the thermal conductivity of polyurethane is significantly lower, usually between 0.018-0.024 W/(m · K). This is due to the closed cell structure of polyurethane, which effectively reduces the heat conduction, convection and radiation. As a result, buildings using polyurethane sandwich panels can maintain warmth during winter and stay cool in summer. This greatly reduces the energy consumption of the building, resulting in significant energy savings and emission reductions.

Polyurethane sandwich panels are also known for their excellent fire resistance. By adding appropriate flame retardants, polyurethane sandwich panels can achieve different fire ratings, such as B1 (flame retardant) or even A2 (non-flammable). During a fire, polyurethane sandwich panels can effectively delay the spread of the fire, reduce heat release and smoke generation, and prevent the spread of the flame. This gives people valuable time to evacuate and prevents further damage to the building, improving its overall safety.

Another advantage of polyurethane sandwich panels is their good water and moisture resistance. Polyurethane is a naturally hydrophobic material, and its closed-cell structure prevents water from penetrating. This, combined with the protection provided by the outer metal sheet, allows the sandwich board to resist erosion from rain, snow, and humid air. It prevents water from entering the temperature retaining core material, avoiding thermal insulation performance decline, mold, rot, and other problems caused by moisture. This ensures the long-term stability and durability of the thermal insulation system.

Polyurethane sandwich panels are also characterized by their high strength and stability. The upper and lower layers of sheet metal provide sufficient strength for the sandwich board to withstand large external forces, such as wind and snow loads, and the weight of people and equipment. The polyurethane core material also gives the sandwich board a certain degree of elasticity and toughness. This makes it more resistant to deformation or damage when subjected to external forces, ensuring the stability of the building structure.

Another advantage of polyurethane sandwich panels is their excellent sound insulation. The panels have a good barrier effect on the transmission of sound, effectively reducing interference from external noise in the indoor environment. Depending on the thickness and density of the sandwich board, sound insulation performance can vary. Generally, the thicker and more moderately dense sandwich boards have better sound insulation performance.

Finally, polyurethane sandwich panels are known for their easy installation features and beautiful appearance. Sandwich panels are usually standardized in size and weight, making them easy to handle and install. A variety of installation methods can be used at construction sites, such as splicing and anchoring. The installation process is simple and fast, resulting in shortened construction periods and reduced construction costs. The outer metal sheet can also come in various colors and surface treatments, such as galvanization and color coating, ensuring that the sandwich board's appearance is beautiful and elegant, meeting the requirements of various architectural styles.

Applications:

Polyurethane sandwich panels are versatile and can be used in various construction projects. Here are some of the application fields for polyurethane sandwich panels:

Polyurethane sandwich panels are widely used in industrial plants, logistics centers, and warehouses to provide stable temperature and humidity conditions for the production environment while reducing heating and cooling costs. Additionally, it meets the requirements of industrial production on building strength and fire performance.

Polyurethane sandwich panels are used in commercial buildings such as shopping malls, supermarkets, hotels, and office buildings. It helps to maintain comfortable indoor environments and reduce energy consumption in shopping malls and supermarkets. It also provides good sound insulation, thermal insulation, and fire protection performance, creating a high-quality environment for customers and office workers in hotels and office buildings.

Polyurethane sandwich panels are used for external wall insulation, roof insulation, and indoor partition of residential buildings. It effectively improves the residential thermal insulation performance, reduces energy consumption, and can protect the roof structure and extend the service life of the waterproof layer of the roof. Additionally, it is both beautiful and can play a certain role in sound insulation when used for indoor partition.

Polyurethane sandwich panels are essential in the construction of cold storages. Its excellent thermal insulation performance ensures temperature stability in the cold storage, reduces the energy consumption of refrigeration equipment, and ensures the storage quality of refrigerated and frozen goods. The moisture-proof and antibacterial properties of the sandwich board also help maintain the sanitary environment of the cold storage.

Polyurethane sandwich panels are also used in agricultural greenhouses and agricultural products warehouses. They help control indoor temperature, humidity, and light to create a suitable environment for crop growth in the greenhouse while maintaining the freshness of agricultural products and extending their storage period in the agricultural products warehouse.
