On September 1st, under the leadership of Noyan Capital, Hengmei Optoelectronics, a subsidiary of Haosheng Technology Group, signed a delivery agreement with South Korean Samsung SDI, officially completing the acquisition and delivery of Samsung SDI's polarizer business. The transaction amount is nearly RMB 6 billion, and the scope of the transaction includes polarizing film production lines, businesses, personnel, and over 1000 intellectual property rights in South Korea and China.

On August 29th, the second globally leading 8.7-meter multi-layer co extruded film material production line of Furong New Materials Co., Ltd. Chengdu base was officially put into operation. This is not only Furong Group's 19th production line nationwide, but also another breakthrough achieved by Sichuan Furong New Materials in just one year after the first production line was put into operation in June 2024.

On August 27th, Changhong High tech announced that the company held the 20th meeting of the third board of directors on August 27th, 2025, and approved the proposal to terminate the establishment of a joint venture company through external investment. In order to meet the development needs of domestic substitution of new materials in the new era and grasp the application needs of downstream national key industries such as new energy vehicles and photovoltaic solar energy, the company and Panjin Shengteng Industrial Development Co., Ltd. (hereinafter referred to as "Panjin Shengteng") have agreed to strengthen cooperation and jointly develop modified substitute materials for photovoltaic POE film and their production processes, as well as hydrogenated nitrile rubber and its production processes.

A seemingly ordinary thin film material, it actually plays a core role in key fields such as optical displays, photovoltaic cells, and electronic packaging. Nowadays, the global market size of this material has exceeded tens of billions of yuan and is continuously expanding at an average annual growth rate of over 3%. It is optical polyester film (PET optical film) - a high-performance polymer material with excellent optical properties, outstanding mechanical strength, and good chemical stability. With its comprehensive performance advantages, it has become a crucial core functional material in modern industrial systems. ‍

On August 28, 2025, global leading polymer manufacturer SenseTime officially completed the acquisition and delivery of Swiss multi-layer film manufacturer Pontacol. This transaction, which took only two months since the signing of the acquisition agreement in June, marks a crucial step in Covestro's strategic layout in the field of specialty films.

On September 4th, Enjie Co., Ltd. (002812) announced the termination of the "Jiangsu Ruijie Power Automotive Lithium Battery Aluminum Plastic Film Industrialization Project" with a total investment of 1.6 billion yuan, and will permanently supplement working capital with the remaining 284 million yuan raised funds and interest. As a non-public offering of stocks in 2023, this project has invested 566 million yuan as of the end of June 2025, of which 477 million yuan has been raised, completing only 62.6% of the planned fundraising amount.

As a national high-tech enterprise, the company focuses on the research and development, production, and sales of plastic films and new materials. Its core products include CPP film, BOPET film, BOPP capacitor film, optical grade film, etc., which are widely used in power generation equipment, ultra-high voltage transmission and transformation, smart grids, consumer electronics, flat panel displays, photovoltaics, packaging and printing, and other fields.

From the approval acceleration of "issuing four certificates in one day" to the engineering miracle of completing construction half a year ahead of schedule, the Nanyang Production Investment Lekai Huaguang High Barrier Membrane Industrialization Project continues to refresh the construction benchmark of Henan's strategic emerging industries with a series of "unexpected" breakthroughs. As a key construction project in Henan Province and the core support of the "7+17" industrial chain cluster in Nanyang City, this industrial giant with a total investment of 2.5 billion yuan and an area of 340 acres is driving China's high barrier film materials to achieve a leap from technological catch-up to global leadership with its "production and investment speed".

At the construction site of Linlong New Materials R&D Base in Dongming County, Shandong Province, the roaring of machines and the towering tower cranes create a busy industrial scene. The 2-micron high-end battery separator production base project with a total investment of 2.5 billion yuan is accelerating. As a key "chain main" project introduced locally, its planned land area is 173 acres, and four wet separator production lines and supporting coating separator production lines will be built. After full operation, it will form a strong production capacity of 1.5 billion square meters of single-layer and three-layer composite lithium-ion battery separators per year. It is expected to achieve an annual output value of 3 billion yuan and an annual tax revenue of 300 million yuan, injecting core material supply capacity into the new energy industry chain.

Thermotropic liquid crystalline polyarylester (TLCP) is a polymer material with broad application prospects. It exhibits excellent thermal and mechanical properties, as well as stable size and low dielectric constant. Therefore, it has broad application potential in high-tech fields such as aerospace, national defense and military industry, fiber optic communication, electronic appliances, etc. However, TLCP is a typical insulating material that has problems such as weak response to external electrical stimuli, single functionality, and poor photothermal conversion efficiency. Therefore, in order to improve the response ability of TLCP to external stimuli, nano composite modification was adopted to enhance its conductivity and photothermal conversion efficiency.

In order to screen excellent bamboo species suitable for promotion and planting in northern Guangxi, the growth adaptability of three medium-sized bamboo species in the genus Dendrocalamus Sapidus, D. minor var. amoenus, and D. minor was compared and analyzed for three consecutive years. The results showed that all three bamboo species exhibited good adaptability to the natural environmental conditions in northern Guangxi. Among them, Qingtian bamboo, as a local bamboo species, has a large number of new bamboo shoots every year and a fast growth rate, making it suitable for large-scale promotion and planting. Based on various growth indicators, the adaptability of the three bamboo species in the northern region of Guangxi is as follows: Sweet bamboo>Flower hanging silk bamboo>Hanging silk bamboo.
