Sandwich Panel Solutions

pu sandwich panel production line

Through the reports of market research institutions, we found that the sandwich panel market is showing a growing trend in Europe, North America and Asia. The global sandwich panel market is expected to grow at a compound annual growth rate of about 5% in the next few years. Especially in the Asia-Pacific region, driven by the construction and refrigeration industries, the demand for sandwich panels is growing rapidly.

Application

In Europe, sandwich panels are mainly used in the construction industry, including residential, commercial and industrial buildings. In North America, sandwich panels are widely used in cold chain logistics such as refrigerated freight vehicles and cold storage. In Asia, the application of sandwich panels is more extensive, covering multiple fields such as construction, refrigeration, transportation, etc.

Sandwich panel production line

The product of the production line – polyurethane composite board is a new type of wall building material with the best insulation, heat insulation, sound insulation, flame retardant, waterproof, lightweight, environmental protection and other functions. It can be widely used in the exterior wall enclosure and decoration of high-rise buildings and high-end office buildings, industrial plants, cold storage, clean rooms and insulated containers. With the rapid development of new building system steel structure buildings, especially the steel structure of urban high-rise buildings and office buildings and various modern industrial plants and public facilities, the demand for environmentally friendly polyurethane composite boards with convenient transportation, simple construction, unique appearance and insulation and decorative effects has soared. Therefore, many foreign construction and building materials machinery and equipment manufacturers have entered this field, which has continuously improved the technical content of polyurethane composite board production lines and continuously updated production processes, and greatly promoted the development of the international steel structure construction industry and new wall material industry.

With the progress of science and technology and the need for building energy conservation, the products produced by the continuous foaming production line of polyurethane composite panels developed by us – composite panels with polyurethane as the core material and with appearance decoration and flame retardant performance effects will definitely replace traditional EPS composite panels and will become the mainstream product of steel structure building materials.
