This paper presents the Liquid Injection Molding (LIM) feasibility of a newly designed liquid EPDM based compounds, Trilene®.  The LIM parts can be used for applications such as electronic, medical and fuel cell seals.  EPDM based compounds are typically not suited for LIM processing, however, with Trilene® based compounds, one part cure is achieved in a few minutes.  These compounds are designed to run on conventional liquid injection machines, with little or no modification.
