Polyethylene terephthalate (PET), with the chemical formula (C10H8O4)n, is synthesized by transesterification of dimethyl terephthalate with ethylene glycol or by esterification with terephthalic acid and ethylene glycol. Dihydroxyethyl phthalate is obtained by polycondensation. It is a crystalline saturated polyester. It is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It is a common resin in life and can be divided into APET, RPET and PETG.

It has excellent physical and mechanical properties in a wide temperature range, the long-term use temperature can reach 120 ° C,and the electrical insulation is excellent. Even at high temperature and high frequency, its electrical properties are still good,but the corona resistance is poor, and the Creep, fatigue resistance, friction resistance and dimensional stability are all good.
