Abstract : The dry blending process used in the production of electrical grade pvc formulations has been studies using a combination of image analysis, microscopic, and spectrochemical techniques. The effects of raw materials, mixing time and temperature, and order of addition were evaluated with respect to the quality of the dry blend and the final product. Changes in particle size distribution at various stages of the dry blending process were followed by image analysis techniques. Optical and scanning electron microscopy were used to assess morphological differences. Spectrochemical techniques were used to indicate chemical changes.
