Sinopec Commissions World's Largest High-End PVA Facility

Sinopec (Sinopec) has commissioned a specialty polyvinyl alcohol (PVA) resin facility with an annual production capacity of 50,000 metric tons at its subsidiary, Chongqing SVW Chemical Co., Ltd. The facility achieved stable operation during startup and produced products meeting quality specifications, with the first shipment already sent to Europe. This new facility increases the site's total PVA production capacity to 210,000 metric tons per year, making it the world's largest single-site production base for high-end PVA. The additional capacity will strengthen the supply of specialty materials used in photovoltaics, electronics, optical films, pharmaceuticals, and other high-value applications. The project was completed in 17 months and recorded 1.98 million safe working hours. A new polymerization process increased production capacity by 40% compared with earlier-generation equipment. The facility also incorporates four exhaust gas and wastewater recovery units and an automated packaging system to improve resource and operational efficiency. SVW Chemical, with over 40 years of experience, offers more than 100 PVA grades and exports over 70 products to more than 40 countries, including Europe and the United States.
