Product Description
PET is prepared by transesterification of dimethyl terephthalate with ethylene glycol or esterification of terephthalate with ethylene glycol, and then polycondensation reaction. It is a crystalline saturated polyester, milky white or light yellow, highly crystalline polymer, smooth and shiny surface, is a common resin in life, has excellent physical and mechanical properties in a wide temperature range, the use temperature can reach 120ºC, excellent electrical insulation, even at high temperature and high frequency, its electrical properties are still good, but poor corona resistance, creep resistance, Fatigue resistance, friction resistance, dimensional stability are very good.
