Abstract
The morphology of the microcellular ethylene-octene copolymer (EOC) of both unfilled and conducting carbon black (Ensaco 250G) filled compounds with different blowing agent and carbon black loading was studied using SEM photomicrographs. The systematic variation in the average, minimum and maximum cell size and cell density with different blowing agent and filler loading was observed. Some physical properties such as relative density, hardness, tensile strength, elongation at break, modulus and tear strength decreases with increase in blowing agent and filler loading. However, the stress relaxation behaviour is found to be independent of blowing agent loading.
