“Through this strategic investment, Covestro aims to further expand capacity and improve the reliability of its global supply of Desmodur 15-based products,” said Philip Bahke, Operations Manager, Covestro Elastomers.

“In addition to meeting our customers’ demand, the Covestro site in Barcelona has been running entirely on renewable energy since the start of 2022,” says Sucheta Govil, Commercial Director of Covestro. “This approach is part of our ambition to reduce our environmental impact while offering our customers better access to our solutions and specialty products.

“We are opening the new production unit for our Desmodur 15 prepolymers in Barcelona alongside the ongoing expansion of our NDI capabilities in the Asia-Pacific region with the Map Ta Phut plant in Thailand”, explains Thomas Braig, Head of Covestro Elastomers. “This new production unit will enable us to support the growth of our customers in the segment of high-end applications of cast polyurethanes. The abbreviation NDI stands for naphthylene diisocyanate.

“Thanks to this new production line, our Vulkollan licensees, as processors of Desmodur 15 prepolymers, will be able to further develop their business,” explains Abdel Arhzaf, head of NDI-Vulkollan. “With these investments, we intend to meet the demand for ultra-high performance elastomers used for superior applications, for example in the material handling industry, as well as for a growing number of engineering.”

Combining the highest mechanical characteristics with dynamic load capacity, Desmodur 15 prepolymer based elastomers are not only one of the strongest cast polyurethanes on the market, they are also as easy to process as conventional prepolymers.
