Resumo
There are two typical ways to modify the properties of a raw polymer. One is polymer blending, which is a low-cost technique that gives rise to new materials with tailored properties. The other is the addition of mineral fillers and fibers, which has been extensively used to modify such properties of thermoplastics as rigidity, strength, durability, and hardness. In the case of immiscible blends, control of the morphology is fundamental; hence, the influence of such parameters as processing conditions and composition, mainly on compatibility, has been studied. In the case of filled polymers, the nature, shape, and size of the particles and their composition are critical parameters that will determine the properties of the composite. In this study, mechanical properties of the high density polyethylene (HDPE) composites filled with silicon dioxide (SiO2), zinc oxide (ZnO) and magnesium hydroxide [Mg(OH)2] were investigated. The structure and properties of the composites are characterized using a scanning electron microscopy (SEM) and Energy dispersive X-ray spectroscopy (EDS). Furthermore, HDPE composites were subjected to examinations to obtain their tensile strengths, yield strengths, elasticity modulus, % elongation, Izod impact strength, hardness, heat deflection temperature (HDT), Vicat softening point and melt flow index (MFI).
