Yuanli Technology polycarbonate diol (PCD) expansion project announced! On January 1, 2025, Shandong Yuanli Technology Co., Ltd.’s polycarbonate diol (PCD) expansion project environmental impact report environmental impact assessment draft was announced (second information disclosure): Project details construction unit: Shandong Yuanli Technology Co., Ltd. project name: Construction Nature of Polycarbonate Diol (PCD) Expansion Project: Expansion construction site: The project is located in the construction content of Zhuliu Chemical Industrial Park in Changle, Weifang City, Shandong Province.: The expansion will be based on the existing polycarbonate diol (PCD) production equipment with an annual output of 2,000 tons and supporting public and auxiliary projects. The project covers an area of ​​about 3,500 square meters. The main content includes the construction and installation of production equipment and packaging rooms, reuse and renovation of C tank area, and reuse of loading and unloading stations. It mainly includes metering equipment, transesterification reaction equipment, post-polymerization reaction equipment, by-product processing equipment, product packaging, storage tanks and other facilities. There are a total of 158 pieces (sets) of equipment in this project. This project expands the polycarbonate diol (PCD) production capacity to 3,000 tons/year (with a by-product of 1,274 tons of methanol/year). Construction time limit: The project construction period is 12 months, and construction is planned to start in May 2025. The project is expected to be completed in May 2026. Project background: Polycarbonate diol is a polymer with multiple carbonate groups in the molecule and hydroxyl groups at both ends of the molecule. It can be used to synthesize a new generation of polycarbonate-based polyurethane. Compared with polyurethane materials synthesized from traditional polyols, polycarbonate polyurethane has excellent mechanical properties, hydrolysis resistance, heat resistance, oxidation resistance and wear resistance. Therefore, the development of polycarbonate diol and corresponding new polycarbonate polyurethane materials has attracted more and more attention from the industry. At present, polycarbonate glycol is widely used as cross-linking agent for water-based coatings for construction and building materials, water-based coatings for automobiles and other chemical additives for construction and building materials. Shandong Yuanli Technology Co., Ltd. already has a polycarbonate diol (PCD) device with a total production capacity of 2,000 tons/year. The device has mature and advanced technology, low reaction pressure, mild temperature, short material residence time, high reaction yield, low consumption, low cost, and good product quality. It is at the leading level at home and abroad. Compared with other manufacturers, it is extremely competitive. At present, Shandong Yuanli Technology Co., Ltd. has accumulated rich experience in construction, production and management for the production of polycarbonate diols, and has also cultivated extensive market resources. To this end, Shandong Yuanli Technology Co., Ltd. plans to invest 40 million yuan in the construction of a polycarbonate diol (PCD) expansion project.
