投资10.5亿！年产3万吨己内酯及聚己内酯项目公示

Core Viewpoint - The article discusses the investment and development of a new biodegradable materials production facility by Weibo Jie Biological Materials (Zhejiang) Co., Ltd., focusing on the production of ε-caprolactone and polycaprolactone, which are essential for various applications in medical and industrial fields [1][2]. Group 1: Project Overview - The total investment for the ε-caprolactone and polycaprolactone production base project is 1.05 billion yuan, covering an area of 112 acres in Shaoxing City [1]. - The project aims to produce 30,000 tons of ε-caprolactone monomer and a series of polycaprolactone products annually, with a two-phase implementation plan [1][2]. - The first phase will complete all construction and establish a production line of 10,000 tons, while the second phase will add an additional 20,000 tons production line [1]. Group 2: Technical Aspects - The production process utilizes self-developed continuous flow technology, overcoming traditional batch reactor methods to address mass production challenges [1]. - ε-caprolactone is a cyclic ester compound crucial for synthesizing biodegradable polyesters, specifically polycaprolactone (PCL), which has excellent biocompatibility and degradability [1]. - PCL is widely used in medical devices, artificial bones, vascular scaffolds, and various industrial applications such as elastomers, synthetic leather, adhesives, and coatings [1]. Group 3: Market Implications - The facility will also produce 90,000 tons of acetic acid as a byproduct annually, indicating a significant contribution to the chemical industry [1]. - The development aligns with national carbon neutrality goals, focusing on the urgent need for environmentally degradable polymers in strategic emerging industries [2].
