Specialty Material Synthesis
Hydrogenated nitrile butyl rubber (HNBR) is a specialty material used in the automotive and petroleum industries. In the early 2000s, Lanxess (then part of Bayer Material Science AG) identified a market need for a more easily processed HNBR and hypothesized that metathesis might provide a solution. Their research ultimately resulted in the development of the low viscosity HNBR product Therban® AT. Therban® AT delivers increased throughput and improved performance to HNBR consumers and in 2006 received the DKG Product Award for rubber innovation. Lanxess has continued to extend its metathesis work and in 2010 announced a new Therban® AT grade that flows 1,000 to 10,000 times more easily than existing HNBR grades. Materia sells its metathesis catalysts to Lanxess under a commercial license. For more information, visit Therban.
