MECHANICAL PROPERTIES OF COMPOSITE THERMOPLASTIC HDPE/NATURAL RUBBER AND PALM OIL BOILER ASH AS A FILLER

This study aims to determine the mechanical properties of natural rubber and High-density polyethylene (HDPE) nanocomposites using 72 nm Palm Oil Boiler Ash (POBA) as filler. The Open mill method is used in the preparation of SIR 20 compounds. Nanocomposite preparation was carried out by varying the composition of nanoparticles (0,5,10,15,20)%. Sample preparation was carried out using 60 cc volume internal mixers with JIS K 6781 standard. The results showed that Young's modulus of thermoplastic elastomer with 20% POBA composition increased to 551.47 MPa and exceeded the pure HD Modulus Young value of 423.58 MPa. Morphological analysis showed that with the addition of nanoparticles, the morphology of the mixture was homogeneous
