The market supply of sandwich materials for wind power is tight, and structural foam materials are the future market development trend.

Common sandwich materials for wind power currently on the market include balsa balsa wood, structural foam materials, etc. Among them, structural foam materials are divided into polyvinyl chloride (PVC) foam, polyethylene terephthalate (PET) foam, poly Styrene (PS) foam, polymethacrylamide (PMI) foam, etc. Among them, structural foam materials are the development trend of sandwich materials for wind power in the future. In the future market development, relevant companies should not only expand production capacity, but also comply with the market trend of environmental protection, greenness and biodegradability.

Wind turbine blades are one of the core components of wind power generation. They are mainly composed of reinforcement materials, sandwich materials, matrix materials, surface coatings and structural adhesives between different parts. Sandwich materials for wind power are one of the main materials of wind turbine blades. Wind turbine blades are the key to determining the performance and production efficiency of wind turbines. Their quality will directly affect the performance and efficiency of wind turbines. Among wind turbine blades, wind power sandwich materials mainly play a role in reducing blade quality, improving blade load capacity, and increasing wind capture. area and ensure the stability of the fan blades.

Balsa balsa is the lightest wood in the world. Due to its excellent performance, balsa balsa has become an irreplaceable high-quality material in wind power interlayers. However, due to the certain growth cycle of balsa wood and the concentration of global production capacity, more than 90% of balsa wood is produced in Ecuador, South America. With the rapid development of the wind power industry, it is difficult for balsa wood to meet the needs of the global wind power industry. At the same time, affected by the COVID-19 epidemic, the supply of balsa wood in South America has become increasingly unstable. Wind turbine blade manufacturers have begun to choose structural foam materials as sandwich materials to alleviate the tight supply of balsa wood. Against this background, the structural foam material market Demand has increased, among which the demand for PVC foam and PET foam has increased significantly.

According to the “2021-2026 Wind Power Sandwich Material Industry Market In-depth Research and Investment Prospect Forecast Analysis Report released by the Industrial Research Center , in recent years, against the background of accelerated energy conversion, the development of the global wind power industry has continued to improve, and the market demand for sandwich materials for wind power has been released. However, due to the unstable supply of balsa balsa wood and high barriers to the structural foam industry, the interlayer for wind power has The material market supply is also becoming increasingly tight.

As a kind of clean energy, under the strategic goals of carbon neutrality and carbon peaking, my country’s wind power installed capacity will continue to increase, among which offshore wind power will become the main growth force in the wind power field. At this stage, my country has become the country with the largest wind power installed capacity in the world. In the future, with the rapid development of the wind power industry and the trend of large-scale wind power blades, the market demand for sandwich materials for wind power will continue to be released, and the industry will have broad room for development in the future.

Industry analysts said that wind power sandwich materials are one of the key materials in wind power blade manufacturing. In recent years, with the global wind power With the development of the industry, the market demand for sandwich materials for wind power continues to be released. Due to the unstable supply of balsa wood and high barriers to the production of structural foam materials, the market supply of sandwich materials for wind power is tightening, and there is broad room for industry development in the future. In the future market development, sandwich materials for wind power will follow the market consumption trend and continue to upgrade in the direction of environmental protection and greening.
