Continental, Kordsa announce sustainable adhesion for textile reinforcements

New car tyres are seen inside the Clairoix Continental tyre factory March 12, 2009 the day after announcements that the company will cut nearly 2,000 jobs and close production at two high-cost European tyre manufacturing sites amid a severe crisis in the auto industry. Production capacity of 8 million car tyres annually in its French site in Clairoix would affect some 1,200 employees.      REUTERS/Benoit Tessier (FRANCE TRANSPORT BUSINESS) - RTXCOHY

Continental and tyre reinforcement company Kordsa are developing a new sustainable adhesion system for bonding textile reinforcing materials to rubber-based compounds, the companies have announced.

The new technology will replace resorcinol and formaldehyde with more eco-friendly chemicals in all of Continental’s tyre segments. Boris Mergell, who heads up worldwide passenger car R&D at Continental, said: “We are therefore planning the progressive introduction of this technology in the production of our tyres across all segments in what is a further substantial step toward greater sustainability.

Numerous suppliers are currently working on solutions of their own and the complexity of the approvals process alone for all of the unique solutions could soon become excessive. That’s why our approach in this collaboration is to make the technology accessible to other suppliers and competitors, thereby laying the foundations for a new adhesion system standard.” Ibrahim Özgür Yıldırım, CTO at Kordsa, added that Kordsa has been working to eliminate the use of resorcinol and formaldehyde since 2008.

Yıldırım explained: “The final formulation is an eco-friendly alternative to resorcinol- and formaldehydebased adhesives widely applied for more than 80 years. Reviewing our massive investments into research in this field and the results obtained, we are absolutely convinced that, in collaboration with Continental, we can make the new technology ready for becoming the new industrial adhesion standard for textile reinforcing materials.” Continental and Kordsa are planning to introduce a free licensing concept for the new adhesion system with more details to be presented at Tyre Expo 2018 in February in Hanover, Germany.
