Comparative Study of Zeolite-Filled LLDPE and HDPE Composite Films
E-mail:
A comparative study of zeolite-filled LLDPE and HDPE composite films has been performed in terms of the filler dispersion, morphology, and the mechanical, rheological, and impact properties. The SEM morphology showed a good dispersion and adhesion of the filled zeolite in the LLDPE and HDPE systems. The HDPE/zeolite composite presents the higher draw ratio and aspect ratio, and has a larger number and bigger area of air holes than appear in the LLDPE system, which shows the most effective composition for diaper applications with a 40 wt% zeolite loading at a 300% draw ratio. The tensile and yield stress increased with the zeolite content in the LLDPE system, but the inverse behavior was observed in the HDPE system. The Young's Modulus gradually increased, whereas the elongation at break was constant up to a certain draw ratio, but decreased at high contents of zeolite in both the LLDPE and HDPE systems. The impact properties of the LLDPE composite improved at up to 40% zeolite content, but they decreased in the HDPE system, implying a weak interfacial interaction in the HDPE system. Morphological observations strongly support the differences in the mechanical properties between the LLDPE and HDPE systems. Based on various properties, zeolites can be good candidates for fillers in each LLDPE and HDPE system for particular purposes.
