INTRODUCTION
Reaction injection molding (RIM) is a process with in-situ polymerization during the shaping operation. It is one of the major developments in polymer processing of the 1970s.
There are several primary reasons for considering use of RIM as a process for molding plastic parts (1): low energy requirement, low cost of mold and equipment, low operating pressure, and mass production capability. Polyurethanes, polyamides, epoxies, polyesters, and hybrid block polymers can be processed in this way. Among them, the most successful commercial application of the RIM technology is with polyurethanes.
Epoxy RIM is slightly behind nylon RIM in ...
