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].
