The advantages of using pet bottle embryo: 1, PET is the main variety of thermoplastic polyester, commonly known as polyester resin. 2, PET is a polycondensation of terephthalic acid and ethylene glycol, together with PBT collectively known as thermoplastic polyester, or saturated polyester. 3. PET is a milky white or pre-yellow highly crystalline polymer with a smooth and shiny surface. 4. PET has good creep resistance, fatigue resistance, friction resistance and dimensional stability, small wear and high hardness, with greater toughness in thermoplastics; 5, PET electrical insulation performance is good, less affected by temperature, but corona resistance is poor. 6, PET non-toxic, weather resistance, chemical resistance, good stability, low water absorption, weak acid and organic solvent resistance.
