Abstract

In this work, the technological characteristics of model compositions for injection molding are evaluated by studying their rheological behavior when changing the content of the main components of the model composition. The influence of the ratios in «paraffin/petroleum resin» and «sevilen/polyethylene wax vapor», and also on the properties of polyvinyl alcohol used as solid filler on the rheology of model compositions of experimental compounds is considered. Based on the results, it was suggested that the ratio of petroleum resin and paraffin should be 2/1, the ratio of polyethylene wax and sevilen 1/1 respectively.
