Abstract
In this paper, each specimen blended at weight proportions of 80% HDPE to 20% EVA, 70% HDPE to 30% EVA, 60% HDPE to 40% EVA, and 50% HDPE to 50% EVA was manufactued respectively. FE-SEM, DSC and XRD analysis were carried out as the means of structural and chemical analysis. From the results of DSC and XRD analysis, the lower contents in blended specimens were, the higher melting temperature and crystallinity of main crystal were. It seems that the phenomena was attributes to themoplastic interpenetrating network effect(TPIPN) in which EVA having low melting point penetrated into HDPE. Also, from the decreasing tendeancy of melting point as a function of blend ration, it was confirmd that above resins have compatibility. The thermal and mechanical performance of proposed insulator were compared with conventional XLPE, main insulating material of CV cable. Also, validity was proved by superior and inferior factor respectively.
