Properties Of Kenaf Bast Powder Filled High Density Polyethylene/Ethylene Propylene Diene Rubber Composites

The properties of thermoplastic elastomer composites of kenaf bast powder filled HDPE/EPDM were investigated. The composites were prepared by melt blending at 70/30 phr ratio of HDPE/EPDM with different filler loading, e.g; 10, 20, 30 and 40 phr. The properties of kenaf bast powder was investigated...
