50-200 Mm Polyurethane Insulating Panel Temperature Resistant

The polyurethane sandwich board represents a new and innovative type of building material. This panel is composed of two layers of metal sheet (commonly made of galvanized steel plate, color steel plate, etc.) and polyurethane hard foam core material. By combining these materials, the polyurethane sandwich board is able to possess both the strength of metal sheet and the excellent performance of polyurethane core material.

The polyurethane rigid foam core material is produced by mixing isocyanate and polyol under specific conditions, which forms a uniform and fine closed cell structure inside. This unique structure offers a wide range of benefits for building construction applications. The production process for sandwich panels is advanced, ensuring that the layers are tightly combined to form a strong and durable whole. This results in high-performance panels that meet the requirements of the construction industry.

Our product boasts a number of important characteristics that make it a top choice for insulation needs.

The thermal conductivity of polyurethane is extremely low, generally between 0.018-0.024 W/(m · K), which is much lower than other traditional insulation materials. This low thermal conductivity benefits from the closed cell structure of polyurethane, which effectively reduces the heat conduction, convection and radiation, so that the building can keep warm in winter and cool in summer, greatly reducing the energy consumption of the building and achieving energy saving and emission reduction.

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

Polyurethane itself is a hydrophobic material, and its closed-cell structure also prevents water penetration. Coupled with the protection of the outer metal sheet, the sandwich board can effectively resist the erosion of rain, snow and humid air, prevent water from entering the interior of the temperature retaining core material, avoid the problem of thermal insulation performance decline, mold, rot and other problems caused by moisture, and ensure the long-term stability of the thermal insulation system.

The upper and lower layers of sheet metal provide enough strength for the sandwich board to withstand large external forces, such as wind loads, snow loads, and the weight of personnel and equipment. At the same time, the polyurethane core material also gives the sandwich board a certain elasticity and toughness, so that it is not easy to deformation or damage when subjected to external forces, to ensure the stability of the building structure.

The polyurethane sandwich board has a good barrier effect on the transmission of sound, can effectively reduce the interference of external noise on the indoor environment, and create a quiet and comfortable living and working space for people. The sound insulation effect depends on the thickness and density of the sandwich board to a certain extent, and the sound insulation performance of the thick and moderate density sandwich board is better.

Polyurethane sandwich panels usually have 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., so that the sandwich board appearance is beautiful and generous, and can meet the needs of different architectural styles. At the same time, the metal sheet and polyurethane core have good durability, can resist the erosion of natural factors such as ultraviolet light, chemical substances, temperature changes, and extend the service life.
