Celanese has shut down an elastomer plant in Ontario, Canada.

On August 10, 2025, Celanese announced at its second-quarter earnings conference call that it plans to close two production plants located in Sarnia, Ontario, Canada and Sempera, Switzerland. 
The factory located in Canada produces the Vamac brand ethylene acrylic ester elastomer (AEM), which is usually used in automotive applications; while the factory in Switzerland produces dispersible latex powder, these organic adhesives are widely used in the fields of building materials and adhesives. 
Celanese stated that the decision to close these two factories would result in savings of approximately $5 million to $10 million by 2026. The operations of these two factories will be integrated into the company's existing manufacturing facilities. 
In 2022, Celanese acquired DuPont's DuPont Transportation and Materials Division for $11 billion. As a result, Celanese obtained a wide range of engineering thermoplastic and elastomer product portfolios, well-known industry brands and intellectual property rights, as well as production assets located around the world and a world-class organizational structure. Among them, it includes the Vamac elastomer production line. 
Scott Richardson, the president and CEO of Celanese, stated in a statement that since the beginning of 2025, generating cash flow has been the company's top priority. "Although the current market demand has not shown any improvement, by continuously implementing cost reduction and efficiency enhancement measures, we are confident that we can continue to create enterprise value."
