This study is to investigate the fabrication of filled polyurethane elastomer tiles by the reaction injection moulding (RIM) process. The base matrix is composed of a crosslinked polyurethane elastomer formed by the reaction between a diisocyanate (MDI) and a polyol (polytetramethylene glycol) and crosslinked by trimethylol propane (TMP). The two fillers investigated were barium sulphate and Expancel which were used to dissipate and scatter sonic waves in acoustic damping applications. [Continues.]
