Polyurea RIM for Improved Fascia Productivity 890337

Since the development of the reaction injection molding (RIM) process in the late 1960's and its application to flexible damage resistant front and rear bumper systems in the mid 1970's, a continual improvement in material performance and process efficiency has been demonstrated. The conversion from glycol extended to amine extended technology in the early 1980's not only provided improved physical properties and productivity but also allowed for the incorporation of reinforcements to improve dimensional stability (RRIM). Incorporation of internal mold release (IMR) technology in the mid 1980's further increased RIM productivity. And now with the introduction of a new generation of polyurea fascia materials, further improvements in quality, productivity and overall economics can be realized. This paper will outline the quality, productivity and economic benefits of these new polyurea systems for automotive fascia applications.
