Abstract :
We examined the mechanical and electrical properties as well as physicochemical analysis of PLA and PET copolymer that is biodegradable plastics. The decreasing rate of tensile strength of PET copolymer became a tendency to look like PP, and was more gradual than the decreasing rate of PLA. The rise of σ of PLA according to the rise in heat was not caused easily from PET copolymer. Dielectric breakdown strength of PLA was high within the range of the temperature that was wider than that of the PET copolymer and LDPE. εT\´ was LDPE < PLA < PET copolymer ≈ PET, and the maximum value of the peak of εT" was PET copolymer > PLA > PET.
