Abstract :
The radiation effects on electrical and mechanical properties of LDPE/EVA blends with various vinyl acetate contents were investigated. Radiation degradation of LDPE/EVA blends was studied using TGA, gelation, volume resistivity, dissipation factor, elongation at break, and elastic modulus. As vinyl acetate contents of LDPE/EVA blends increased, the electrical insulation characteristics were deteriorated but the flexibility was improved. As irradiation dose was increased, the electrical insulation characteristics were improved, but the flexibility was deteriorated
