Investigation of High Velocity Impact Resistance of HIIPS/Clay Nano Composite

A series of polymer-clay nano composite (PCN) materials, consisting of thermoplastic high impact polystyrene (HIPS) sample and dispersing inorganic organoclay platelets, were successfully prepared. First, nano composite was prepared by extrusion of the raw HIPS and organoclay powder to a 20% master batch, followed by dispersing the organophilic clay into a HIPS basis through the melt intercalation approach performed by a twin-screw internal mixer. In this study, it is found that the high velocity impact resistance of HIPS to be effectively enhanced by the incorporation of low loading organophilic clay platelets
