Leverkusen – “This is another important step into an even more sustainable future with Lanxess,” said Torsten Derr, Head of the business unit Keltan Elastomers (KEL).

The German pioneer in synthetic rubbers development has invested roughly EUR 12 million to convert the production line from conventional Ziegler-Natta chemistry to its innovative ACE-process. The new line – EPT 3 – has a capacity of 95,000 metric tons per year. This is more than half of the total capacity at that plant. It is currently the world’s largest EPDM plant with an annual capacity of 180,000 metric tons.

The ACE process, utilizing outstandingly active catalysts, enables the company to deliver an extraordinarily broad range of proven, high-quality EPM and EPDM grades – in consistent quality, chlorine-free and with high degrees of purity. Above that, the process consumes less energy and produces no catalyst waste, what makes a deashing step obsolete.

EPDM-Production with ACE-Techology

The ACE process not only offers Lanxess a more sustainable process. It also makes higher value EPDM grades accessible that were beyond reach of conventional technologies. “The ACE catalyst system allows for the production of the complete EPDM grade portfolio, including a wide range of monomer compositions and molecular weights,” said Derr.

And the ACE story will be going global soon: “Our Changzhou plant in Jiangsu Province, China, starting up in 2015, will also work with ACE-technology. We are prepared to lead EPDM into a bright future,“ said Derr.

The plant will have a capacity of 160,000 metric tons per year and represents an investment of EUR 235 million, the largest capex project the company has made in China to date.
