Abstract: High velocity jet impingement mixing is a unique operation of the reaction injection molding process. The quality of mixing depends on processing parameters for a given system, and can have significant effect on the properties of the product. We have compared three methods used for characterization of mixing quality reported in the literature for a cross-linking polyurethane system p r e cessed on an industrial scale high pressure RIM machine, with an Ltype mixhead. The methods are based on, (i) visual appear…
