As the material of choice for automotive fascias switches from polyurethanes to polyureas, the capability of making large parts on existing equipment iss carificed. Thus, a molder is forced to modify his equipment to an increased injection rate. With recent developments in polyurea technology, however, the capability to make large parts on existing equipment is returned. This paper surveys the development of polyurea technology leading up to this most recent development. Processing, physical properties, and filler effects are included. Polyurea RIM fascia materials offer stiffer parts at demold, improved surface appearance, and improved dimensional and thermal stability. With the development described in this paper, injection times similar to polyurethane materials can be added to these benefits.
