Laminated transparent Plastic Film Roll

PET film, namely polyethylene terephthalate film, is widely used in packaging and textile. The following is the academic explanation: pet is polyethylene terephthalate, with the chemical formula of - OCH2-CH2OCOC6H4CO - English name: polyethylene terephthalate, abbreviated as PET, is a high polymer, which is derived from the dehydration and condensation reaction of ethylene terephthalate. Ethylene terephthalate is obtained by esterification of terephthalic acid and ethylene glycol. PET is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range. Its long-term use temperature can reach 120 ℃, and its electrical insulation is excellent. Even under high temperature and high frequency, its electrical performance is still good, but its corona resistance is poor, creep resistance, fatigue resistance, friction resistance, and dimensional stability are good.
