Commitment to supporting customer growth
The capacity expansion at Covestro Integrated Site Shanghai (CISS) comes in response to growing customer demand for TDI, a key component used primarily in flexible foams for furniture, mattresses and automotive applications. The debottlenecking project was completed on schedule and will enable Covestro to provide more reliable supply to customers throughout the region.
"This investment demonstrates our commitment to supporting our customers' growth in Asia Pacific, particularly in China and the broader region. By expanding our TDI capacity in Shanghai, we ensure reliable supply to meet increasing market demand while reinforcing our position as a preferred partner for the furniture and automotive industries," said Xiaobin Zhong, Covestro's head of Performance Materials Sales in the Asia Pacific region.
The site, located in the Shanghai Chemical Industry Park, is one of Covestro's largest production facilities worldwide. The successful debottlenecking project involved optimizing existing production processes and infrastructure rather than building new production lines, resulting in a more resource-efficient approach to capacity expansion.
