Physical and Chemical Properties of Cross Linked Polyethylene
Cross Linked Polyethylene의 물리적 및 화학적 성질
Abstract
XLPE (Cross-Linked Polyethylene) which has good electric and physical characteristic is ideal material for Insulating material with force high volumetric resistance arid high dielectric constant. We study abort electric characteristics of XLPE by DCP and TMPTA content ration. DCP (Dicumylperoxide), which was used cross-linked agent contest, was changed from 1.0 to 0.5phr. TMPTA (Trimethyl-olpropane), which was used co cross-linked agent content, was changed from 0.5 to 1.5phr. Thermal analysis by DSC in order to observe tendency of Tg according to DCP and TMPTA content. Specimen 3 that content DCP 2.0phr and TMPTA 0.5phr has the highest value Breakdown strength cf specimen 3 (DCP 2.Ophr, TMPTA 1.0phr) is the highest, value and it increased in specific inductive capacity. This due to difference from cross-linked state by DCP and TMPTA content ratio.
