Zhejiang Changhong Biomedical Materials’ project to produce 50,000 tons per year of high-end fiber elastomer materials, along with a facility for manufacturing 100,000 tons per year of PBAT black masterbatches, with an investment of 1.03 billion yuan
Thread Content
Project Name: Zhejiang Changhong Biomedical Materials Co., Ltd. – Project for the annual production of 50,000 tons of high-end fiber elastomer materials, along with a facility for the annual production of 100,000 tons of PBAT black masterbatches. Launch Date: December 24, 2025. Location: Zhejiang. Industry/Project Type: Chemicals and Pharmaceuticals/Chemical Raw Materials and Chemical Products/Synthetic Materials； New infrastructure and new industries/new materials project: Owner – Zhejiang Changhong Biomedical Materials Co., Ltd. Total investment: 1,030 million yuan. Current progress: The project has been registered. Location of construction: No. 618, Mingxinling Road, Yanhu Sub-district, Zhejiang Province. Scope of construction: The facility is designed to produce 50,000 tons per year of high-end fiber elastomer materials, along with 100,000 tons per year of PBAT black masterbatch. Among them, the high-end fiber elastomer plant is designed to operate for 8,000 hours per year; its design elasticity ranges from 50% to 110%. The products produced include 50,000 tons of poly**furan (MW1800/MW2000), 2,250 tons of low-molecular-weight P250 (a by-product), and 7,500 tons of crude methyl acetate (75%, also a by-product). The PBAT black masterbatch production facility employs a dual-heater process and is designed with 3 production lines (1 line with a capacity of 50,000 tons per year, 1 line with 30,000 tons per year, and 1 line with 20,000 tons per year). The designed annual operating time is 8,000 hours, with a capacity flexibility range of 50% to 110%. The products produced are hard black masterbatches such as N220 and N330, which are used in PBAT-modified products as well as in film blowing processes. Progress milestone: December 23, 2025 – Project registration completed (Project registration)
