PU Sandwich Panel

What parts does the PU Sandwich Panel consist of and what are the characteristics and functions of each part?

PU Sandwich Panel (PU Sandwich Panel) is mainly composed of metal panels, polyurethane core materials and possible surface coatings. Each part has unique characteristics and functions, which together ensure the overall performance and application effect of the sandwich panel.
First of all, the metal panel is the outer layer of the PU sandwich panel. Common materials include galvanized steel sheets, aluminum-zinc alloy coated steel sheets, etc. These metal panels have excellent corrosion resistance and mechanical strength to withstand corrosion, weathering and mechanical damage in the external environment. The flatness and smoothness of the metal panels also provide the sandwich panel with a good appearance, increasing its aesthetics and applicability.
Secondly, polyurethane core material is the core component of PU sandwich panel. Polyurethane is an excellent thermal insulation material with a closed-cell structure and low thermal conductivity, so it can effectively reduce heat conduction and achieve excellent thermal insulation effects. In addition, the polyurethane core material also has good sound insulation properties, which can effectively isolate external noise and create a quiet and comfortable environment. At the same time, the polyurethane core material has excellent compressive strength and resilience, which can maintain the overall structural stability of the sandwich panel and resist the impact of external forces.
In addition to metal panels and polyurethane core materials, PU sandwich panels can also be coated with a special coating on the outer surface of the metal panels according to requirements. These coatings can be in various colors and follow common color standards such as RAL, etc. Surface coatings can not only enhance the corrosion resistance and durability of metal panels, but also provide personalized appearance effects to meet architectural style and design requirements.
To sum up, each part of the PU sandwich panel has its own unique characteristics and functions. Metal panels provide protection and aesthetics, a polyurethane core provides excellent insulation and sound insulation, and a surface coating further enhances corrosion resistance and aesthetics. These parts work together to form PU sandwich panels, an efficient and reliable building material that is widely used in construction, industry and refrigeration.
