CHARACTERIZATION OF LUBRICANT POLYETHYLENE WAXES

Abstract

Polymer processing is become easy while using lubricant in a proper way. Hence viscosity reduction and gelation behavior/release effect of lubricants help the production speed and quality. In this manner by the growing need for lubricant characterization two technical-grade polyethylene (PE) waxes were investigated. PE is one of the most used lubricant and study by characterizing them using Fourier Transform Infrared (FT-IR) spectrophotometry, Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Differential Scanning Calorimetry (DSC) and Thermogravimetric analysis (TGA) to elucidate their structural, molecular and thermal characteristics in order to assess their effectiveness and suitability as lubricants in carpet manufacturing.
