Core Viewpoint - The article highlights the significant advancements made by Zhongke Kele in the production and commercialization of high-end polyolefin materials, particularly the successful launch of ethylene-based polyolefin elastomers (EPOE) in China, marking a shift from technology development to market application [1][2]. Group 1: Product Development and Production - Zhongke Kele's innovative E-POE process utilizes a completely original nickel-based catalyst technology, allowing for the production of EPOE using ethylene as the sole raw material, along with domestically sourced additives and conventional polymerization equipment [2]. - The company has successfully transitioned from laboratory-scale testing to pilot production, with a 5000 tons/year EPOE pilot plant expected to be completed by November 2024, demonstrating rapid progress in scaling up production [3]. Group 2: Future Projects and Investments - In 2025, Zhongke Kele plans to advance multiple projects, including a total investment of 7.5 million yuan for an advanced polymer materials testing line in Anhui, which will have various experimental capabilities [4]. - The construction of the world's first 300,000 tons/year EPOE production facility by Shandong Dongming Petrochemical Group has commenced, with an estimated total investment of approximately 4 billion yuan [4]. - The second phase of Zhongke Kele's polyolefin elastomer packaging materials headquarters project has received approval, aiming to produce materials for photovoltaic encapsulation films and enhance the domestic production of high-end polyolefins [4].
