Functional properties of PET film are introduced

Polyethylene terephthalate oxalic ester chemical formula for - OCH2 - CH2OCOC6H4CO - English name: polyethylene terephthalate, or PET, for high polymer, by terephthalate dehydration condensation reaction.Ethyl terephthalate is obtained by esterification of terephthalic acid and ethylene glycol.PET is a milky or light yellow, highly crystalline polymer with a smooth, shiny surface.It has excellent physical and mechanical properties in a wide range of temperature, the long-term use temperature can reach 120℃, excellent electrical insulation, even at high temperature and high frequency, its electrical performance is still good, but poor corona resistance, creep resistance, fatigue resistance, friction resistance, dimensional stability are very good.PET film is also known as high temperature resistant polyester film.It has excellent physical properties, chemical properties and dimensional stability, transparency, recyclability, can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial film, packaging decoration, screen protection, optical grade mirror surface protection and other fields.
