EPDM for Exterior Trim Applications

The purpose of this paper is to review the current status of EPDM from the standpoint of applicable properties, availability, custom molder capabilities and commercial implications. Current EPDM applications are described and, where appropriate, comparisons are made with reaction injection molded urethane (RIM) which, to date, has had the broadest usage in flexible fascia. In addition, anticipated developments in EPDM technology are described to give the automotive engineer and stylist an insight into possible EPDM capabilities in the future.
