Physical properties of garnet-filled polyurethane foam composite

Garnet-filled polyurethane foam composite was prepared by solvent-free reac tion. Density, hardness, and compression strength were measured to study it s basic physical properties. Percent volume loss and arithmetical mean surf ace roughness were investigated as an abrasion property to determine its po tentiality as an abrasive and establish a relationship between basic proper ties and abrasion properties. These properties were measured as functions o f blowing agent content, and garnet was used as filler. The particle size o f the garnet and the polyol mixing ratio mere also changed to investigate t he dependence of properties on formulation. (C) 2000 John Wiley & Sons, Inc .
