DSM will start producing ethylene propylene diene rubber (EPDM) next year with Nova Chemicals' single-site catalyst technology. "This exciting new generation of catalysts allows us to tailor-make specialty EPDMs that offer characteristics that cannot be reached with Ziegler-Natta technology," says DSM Elastomers President Bob Hartmayer.
