Geneva,Switzerland -- E.I. DuPont de Nemours and Company, Inc., and Evonik Degussa GmbH of Marl, Germany, have signed a license agreement which grants DuPont sole, worldwide access to the multi-shot or 2K molding technology patented by Evonik for nylon 6,6 and nylon 6.
The licensed technology enables the elimination of process steps in the production of two-component assemblies combining DuPont Vamac ethylene acrylic elastomer (AEM) or DuPont Viton fluoroelastomers (FKM) with DuPont Zytel nylon resins, leading to cost and processing efficiencies as well as enhanced part quality and reliability.
Patrick Cazuc, Global Marketing Manager, DuPont Performance Polymers, said, "Being the sole licensee under Evonik's 2K overmolding technology for nylon 6,6 and 6 allows us and our customers to achieve important quality, cost and performance gains in two-component moldings of Zytel nylon directly bonded with Vamac or Viton elastomers, for demanding under the hood applications,â€
The technology also allows automakers and Tier 1 suppliers to mount the parts more easily due to the exact positioning of the elastomeric seal or gasket onto the thermoplastic part, thus reducing the risk of potential misplacement and consequent leakage.
