Structural RIM-Polyurethane RIM Broadens Its Applications and Markets

Since its commercial introduction, Reaction Injection Molding has found advantages in Automotive, Industrial and Consumer markets, primarily in large part applications. However, the limitations of traditional polyurethane RIM materials have limited the use of the process to non-structural parts.

Today, with new advances in polyurethane chemistry, combined with the technology of long fiber reinforcement and RIM processing advantages, structural applications for the construction equipment industry are a viable alternative.

This paper will offer a snap shot review of the emergence of polyurethane RIM technology and the markets it serves.
