Core Viewpoint - The article discusses the investment by Sinopec Yizheng Chemical Fiber Co., Ltd. in a project to develop a green bio-based PO3G-PTT high-performance elastomer, highlighting the significance of bio-based materials in the chemical industry and their potential for sustainable development [1][2]. Project Overview - Project Name: Green Bio-based PO3G Preparation and PO3G-PTT High-Performance Elastomer Product Development Project - Industry Category: C2651 Primary Form Plastics and Synthetic Resins Manufacturing - Project Nature: Reconstruction - Total Investment: 47.378 million yuan, with 1.47 million yuan allocated for environmental protection, accounting for 3.1% of the total investment - Construction Area: 350 square meters - Construction Period: 12 months - Production Capacity: 5,000 tons per year [2][3]. Technical Innovations - The project introduces bio-based PO3G (polytrimethylene ether glycol) as a key raw material, which is derived from plant fermentation and can replace petroleum-based polyols [3][4]. - Innovations include: 1. Controlled preparation of bio-based monomers, ensuring quality impacts polymer performance 2. Copolyester molecular structure design to enhance material properties 3. Flexible production processes to meet diverse market demands [8]. Competitive Advantages - Yizheng Chemical Fiber has a robust production capacity, including 3 million tons of PTA and 3.1 million tons of polyester per year, which supports the integration of the bio-based PTT material route [9][10]. - The strategic layout includes a complete industrial chain from PX-PTA-PET/PTT, enhancing competitiveness and ensuring raw material supply for bio-based PTT production [11]. - The project aims to extend the polyester industry chain and develop high-value-added products, contributing to the company's transformation and upgrade strategy [11].
