Polyethylene 계열 절연재료의 환경적·기계적 특성

초록

In this study, four kinds of specimens of PE(polyethylene)-based insulating materials were prepared forselecting the optimum insulation materials in a wet environment. The specimens were tested by various methods, theanti tracking test, the transmittance test in the water vapor transmittance(WVT) and the abrasion resistive test, etc. TheHDPE(high-density polyethylene) specimen was showed excellent property in the tracking resistance test and the lowesttransmittance in water vapor transmittance test. In the abrasion resistive test, the LLDPE(linear low-densitypolyethylene) and MDPE(medium-density Polyethylene) were showed excellent mechanical properties. The value ofcut-through resistance for MDPE and HDPE were superior to that for LLDPE and LDPE(low-density polyethylene).
