Influence of Kenaf (KNF) Loading on Processing Torque and Water Absorption Properties of KNF-Filled Linear Low-Density Polyethylene/Poly (vinyl alcohol) (LLDPE/PVA) Composites

The KNF-filled linear low-density polyethylene composites were prepared by using an internal mixer (Thermo Haake Polydrive) at 150 °C and 50 rpm rotor speed. The composites were mixed with different KNF loading, i.e., 10, 20, 30 and 40 phr. The effects of KNF loading on processing torque and water absorption of the composites were investigated. The results indicated that stabilization torque and water absorption were increased with increasing KNF loading. Composites with higher KNF loading demonstrate higher equilibrium water absorption.
