The successful application of reaction injection molded vertical body panels for the Pontiac Fiero will encourage future applications of synthetic body panels. The desire for further advances in part quality and productivity requires additional improvements in body panel material technology.One technology which has shown the potential for an improved property profile is polyurea RIM. However, previous conventional polyurea formulations have been limited in flow time, processing conditions, and shrinkage control.This paper summarizes the development of Bayflex 150, a flowable polyurea RIM formulation. It provides all the property advantages of previous polyureas, but overcomes their processing limitations. Its combination of physical properties and processing characteristics should make it the best candidate for future body panel applications.
