It is a polycondensate of terephthalic acid and ethylene glycol, collectively referred to as thermoplastic polyester or saturated polyester together with PBT. PET is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, good friction resistance and dimensional stability, low abrasion and high hardness, with the greatest toughness among thermoplastics; good electrical insulation performance, low temperature influence, but poor corona resistance. Non-toxic, weather resistance, good chemical resistance, low water absorption, resistance to weak acids and organic solvents.
In many fields, plastic bottles are an important form of packaging. Beverages, food, cosmetics, medicines, daily necessities and chemical raw materials can all be stored in plastic bottles.
