Zhejiang huashuai special new 1.8 billion layout aviation PMMA, annual output of 35000 tons

On September 3, the Jiaxing Municipal People's Government of the Jiaxing Municipal Committee of the Communist Party of China officially issued an announcement to approve the EIA documents for the construction project of Zhejiang Huashuate New Material Technology Co., Ltd. with an annual output of 35000 tons of aviation PMMA transparent materials, marking the domestic aviation-grade PMMA A key step has been taken in the industrialization process.

The expansion project is located in shendang Town, Haiyan County, to Jiujiabang Road in the east and Wenchang Bridge Port in the north, with a total investment of 180 million yuan, of which environmental protection investment is 2.5 million yuan, accounting for 1.39 percent, reflecting the enterprise's emphasis on green production. The project plans to add 20574 square meters of land, build new aviation board production workshop, post-processing workshop, polymerization building and other supporting facilities, with a total construction area of 25500 square meters and a reasonable building density.

From the perspective of capacity planning, the project will add 2 new aviation PMMA transparent material production lines to form an annual production capacity of 35000 tons of aircraft portholes. According to the investment intensity, the investment per ton of production capacity is about 51400 yuan, which reflects the technology-intensive characteristics and higher equipment requirements of the aviation-grade PMMA production line. The successful approval of the project will not only fill the gap of domestic aviation PMMA high-end production capacity, but also provide an important guarantee for the security of China's aviation material supply chain.

PMMA (polymethyl methacrylate) material, also known as acrylic or plexiglass, is an important plastic polymer material developed earlier, with excellent transparency, chemical stability and weather resistance, and is known as the most excellent material in synthetic transparent materials so far.

Aviation PMMA transparent material is known as the "crown jewel" of the modern aviation industry, which stems from its irreplaceability in the key components of the aircraft. As the core material for the manufacture of aircraft canopy, windshield, porthole and other aviation transparent components, the performance of aviation PMMA is directly related to the safety, reliability and comfort of the aircraft. Compared with ordinary PMMA, aviation-grade products face extremely demanding technical requirements.

From a technical point of view, aviation PMMA must bear the huge structural load generated by the pressure difference between the inside and outside of the cockpit and maintain structural integrity in the high-altitude and low-pressure environment. At the same time, as the speed of modern aircraft continues to increase, materials also need to withstand the thermal shock caused by aerodynamic heating during high-speed flight, as well as the complex thermal effects of transient or long-term under various flight conditions. For windshield components, it is more necessary to have multiple functional characteristics such as de-icing, anti-fog, anti-bird impact, static discharge, etc., and the technical complexity is extremely high.

These stringent performance requirements make aviation PMMA the technical commanding point of the material industry, and it is also a strategic material field that countries focus on. With the rapid development of the global aviation industry, especially the continuous growth of the number of commercial aircraft, the demand for aviation PMMA market has shown a steady upward trend.

at present, global PMMA manufacturers are mainly concentrated in Asia, North America and Western Europe. The largest production capacity companies include industry giants such as Roma, Chi Mei, Mitsubishi, Sumitomo and Arkema. By virtue of first-mover advantages and technology accumulation, these enterprises occupy a dominant position in the high-end PMMA market, especially in the field of aviation-grade products.

China's PMMA industry presents the characteristics of "big but not strong. Although the total production capacity of PMMA in China is large, the product structure is mainly in the middle and low end, and there are still obvious core technology shortcomings in the field of high-end optical materials. High-end PMMA production capacity is not enough to meet market demand, the formation of low-end overcapacity, high-end still need to import structural contradictions.

According to data from the General Administration of Customs, China's PMMA imports reached 162700 tons in 2024, which clearly reflects the supply and demand gap in the domestic high-end PMMA market. Imported products are mainly concentrated in high value-added fields such as optical grade, electronic grade and aviation grade, and the price is usually several times or even more than ten times that of ordinary grade products.

From the perspective of industrial development trends, localization substitution is accelerating. In recent years, domestic enterprises have successively broken through optical-grade PMMA production technology, and have continuously improved product quality and stability. The approval of Zhejiang Huashuai's new aviation PMMA project represents the extension of the localization process to a higher end.
