ABSTRACT: 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 oncentrations.
