Core Viewpoint - The article highlights the successful completion of the approval process for Guo'en Co., Ltd.'s "annual production of 20,000 m² aviation-grade acrylic glass project," marking a significant step in the domestic production of aviation-grade transparent materials in China [2]. Group 1: Project Overview - The project involves a total investment of 560 million yuan and is located at Guo'en's headquarters in Qingdao, focusing on the production of cross-linked polymethyl methacrylate acrylic glass (CPMMA) [2]. - The project plans to establish production workshops, storage facilities, and various auxiliary buildings, along with the acquisition of over 200 advanced production equipment, including pressure machines and multi-directional stretching devices [2]. - Upon reaching full production capacity, the project is expected to produce 20,000 square meters of aviation-grade acrylic glass sheets and stretching sheets annually for aircraft and other aviation applications [2]. Group 2: Material Characteristics and Applications - CPMMA is created through a chemical cross-linking process that forms a unique three-dimensional network structure, significantly enhancing mechanical strength, heat resistance, and weather resistance while maintaining high transparency [3]. - Beyond the aerospace sector, CPMMA has extensive application prospects in high-end optical and display technologies, medical devices, industrial and renewable energy fields, and is also ideal for high-precision modeling and 3D printing [3].

Group 1 - The core viewpoint of the article is that Guoen Co., Ltd. has received approval for its "annual production of 20,000㎡ aviation-grade acrylic glass project," marking a significant step into the industrialization of high-end aviation transparent materials [1][2] - The project involves an investment of 560 million yuan and will be located at the company's headquarters in Qingdao, aiming to achieve comprehensive localization and self-control of aviation-grade transparent materials, providing critical material support for China's aerospace and low-altitude economy development [1][2] - Aviation-grade cross-linked polymethyl methacrylate acrylic glass (CPMMA) is identified as a key material for supporting strategic emerging industries such as aerospace and low-altitude economy, characterized by over 93% high light transmittance, superior mechanical strength, heat resistance, and weather resistance [1][2] Group 2 - Upon completion, Guoen Co., Ltd. will have an annual production capacity of 20,000㎡ for aviation-grade cast sheets and stretched sheets, positioning itself as one of the few domestic suppliers capable of mass-producing aviation transparent materials that meet airworthiness standards [2] - The products will primarily serve high-growth sectors such as domestic large aircraft, high-end drones, and electric vertical takeoff and landing vehicles (eVTOL), with further expansion into high-end rail transportation, special vehicles, and precision instrument panels [2] - The implementation of this project is a strategic move for Guoen Co., Ltd. to enter the high-end aviation materials sector and is a crucial step in promoting vertical integration of the industry chain and building a self-controlled material system [2]
