Mechanical, thermal and processing properties of oil palm empty fruit bunch-filled impact modified unplasticised poly (vinyl chloride) composites

The main objective of this study is to investigate the effects of EFB filler and two types of impact modifiers on mechanical and thermal properties, and processability of PVC-U composites. Two methods were used to prepare the samples, i.e., compression moulding and single screw extrusion. A torque r...
