Studies on the Effect of Concentration of Mica on Properties of Polyester Thermoplastic Elastomer Composites

September 11, 2020 Engineering 0

Particulate filled polymer composites are becoming attractive because of their wide applications and
low cost. In this study the effects of mica with varying concentration on the mechanical, thermal,
electrical, rheological and morphological properties of polyester thermoplastic elastomer (Hytrel®)
was investigated. Composites of Hytrel® with varying concentrations (viz. 5 to 40 weight %) of mica
were prepared by twin screw extrusion. Mechanical properties such as flexural strength and modulus
were found to increase with mica concentration, whereas tensile strength was found to decrease at
higher concentrations. Electrical and thermal properties of composite were found to increase with filler
concentration. Morphological studies revealed that there is a good dispersion of filler in the polymer
matrix at lower concentrations.
