Polyethylene terephthalate is the most important variety of thermoplastic polyesters. It has creep resistance, fatigue resistance, good friction resistance and dimensional stability, low abrasion and high hardness, and has the greatest toughness among thermoplastics; It has good electrical insulation and is not affected by temperature, but it has poor corona resistance. Non-toxic, weather resistance, good chemical resistance stability, low water absorption, resistance to weak acids and organic solvent.
