PET Film Sell Well Pet Plastic Transparent

PET film is polyethylene terephthalate film, which is widely used in packaging and textiles. The following is an academic explanation: pet is polyethylene terephthalate. The chemical formula is -OCH2-CH2OCOC6H4CO- English name: polyethylene terephthalate, PET for short, is a high polymer, which is derived from the dehydration condensation reaction of ethylene terephthalate. Ethylene terephthalate is obtained by esterification of terephthalic acid and ethylene glycol. PET is an opalescent or pale yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range, the long-term use temperature can reach 120 ° C, and the electrical insulation is excellent. Even at high temperature and high frequency, its electrical properties are still good, but the corona resistance is poor, and the Creep, fatigue resistance, friction resistance and dimensional stability are all good.
