The PET business card was exchanged with ethylene terephthalate and ethylene glycol or to first synthesize phenylene terephthalic acid with ethylene glycol esterification, and then the polycondensation reaction was obtained, and the PET business card was Milky white or front yellow highly crystalline polymer, smooth surface smooth and lustrous. Wheat resistance, resistance fatigue, abrasion resistance, and have good stability, high wear, high hardness, and has the greatest toughness in thermoplastic.
The polyethylene terephthalate is the most important variety in the thermoplastic polyester, and the Polyethylene Terephthalate is referred to as PET or PEIT (hereinafter, or called PET), commonly known as polyester resin. It is a polycondensate of terephthalic acid with ethylene glycol, which is collectively referred to as a thermoplastic polyester together with PBT, or a saturated polyester.
The PET business card has good mechanical properties, and the impact strength is 3 to 5 times the other films, and the ability to resist.
