Polyurethane rigid foam is the core in these kinds of panels. A special feature of polyurethanes is their method of production. Generally, metering and mixing four or more streams of liquid components containing polyurethane precursors at the processing stage produce polyurethanes. Thus, the final, high molecular weight polymer is normally manufactured by the manufacture of Sandwich Panel who has a PU sandwich panel production line. In the production line of sandwich panel, one section is dedicated to performing this process, called “PU Foaming Machine” or “Metering Machine”.
advantage
1.Polyurethane sandwich panel has good fire resistance
2.Wide range of temperature
3.Fast and convenient installation, short construction period, good comprehensive benefits
4.Excellent thermal insulation. Thermal conductivity of panels with polyisocyanurate foam core is λ = 0,022 W/m*K.
5.Excellent protection against weather conditions, maintaining properties and appearance for many years. When coating is properly selected according to local 6.conditions, several years’ durability of panels can be reached without any problem.
7.Complete seal against precipitations, snow and dampness. Perfectly finished joints ensure complete waterproofness for many years, if installation standards are followed.
peculiarity
The high flexural bearing capacity of the polyurethane wall panel makes the wall have better mechanical properties and thermal insulation properties, while reducing the need for auxiliary steel structure.
Simple construction: polyurethane sandwich plate has the characteristics of standardized production and on-site assembly, convenient installation, can improve the construction efficiency.
Corrosion resistance: The panel of polyurethane sandwich plate has good corrosion resistance, can resist the erosion of acid, alkali, salt and other corrosive media, and is suitable for use in harsh environments.
