Internal mold release offers the potential for significant increases in the productivity of reaction injection molded polyurethanes. This paper discusses the requirements for internal release formulations, their economic advantages, and various approaches which are under development. Mathematical modelling indicates that approaches which provide around 20 moldings per application of external spray will offer a high percentage of the maximum possible productivity benefit that could be attained with no spray requirement.
