Polyethylene resins (PE), having extremely superior electric characteristics, are widely used as an insulating material of cables for high voltage. However, cables such as PE cables can deteriorate by oxide. Therefore, materials with less oxide deterioration urgently need to be developed. As a valuation of oxide deterioration, some parameters for chemiluminescence are known to have a strong correlation with results of the stability test of high polymer materials. From the chemiluminescence measurement of samples, in which PE with an annex of 0.3 (per hundred resin, phr) vapor grown carbon fiber(VGCF) was treated by heat at 120°C for 72 hours, the luminosity decreased by approximately 1/6 of PE with non-annex. Moreover, in the case of an annex of 5 phr for PE, the luminosity became approximately 1/30 of PE with non-annex, which reveals that PE with an annex of 5 phr has extremely low oxide deterioration. This indicates that an annex of VGCF can decrease the amount of chemiluninescence of PE, which improves resistance against oxidization.
