Effect of Compounding Process Parameters Selection on Conductivity Level of Polymer Blends with Aluminium oxide as nanofiller for HVDC Cable Application

Abstract

The usage of polymer nanocomposite as electrical insulating materials has gained more interest and start to be examined by the various researchers. The aims are same which is, to improve the electrical and mechanical performance of the insulation materials for high voltage application purposes. This paper will present the early finding on using compounding polymer-based nanocomposite as high voltage direct current (HVDC) cable insulating material. In this paper, the Design of Experiment (DOE) is the approach used in compounding the small amount of high-density polyethylene (HDPE) added into linear low-density polyethylene (LLDPE) blends with aluminium oxide (Al2O3) as nanofillers. The effect of several parameters during the compounding process such as concentrations of the material, rotations per minute of the screw speed and the temperature used on conductivity value of the material will be discussed in this paper. In the end, the best parameter for the compounding process can be identify and conclude.
