Hanwha Solutions Corp. (Seoul) plans to reduce its polyvinyl chloride (PVC) operating rate, including both suspension and paste resins, from the current level of around 80% to 60%-70% starting mid-June, a company source told Platts, part of S&P Global Energy, on June 10. “The operating rate is currently around 80% but will be reduced to approximately 60%-70% from mid-June due to negative margins,” the source said.
