Polyethylene Terephthalate/PET CAS:25038-59-9 Description
Polyethylene terephthalate is the most important variety of thermoplastic polyester, commonly known as polyester resin. It is prepared by transesterifying dimethyl terephthalate with ethylene glycol or esterifying terephthalic acid with ethylene glycol to synthesize bishydroxyethyl terephthalate, followed by polycondensation. Together with PBT, it is collectively referred to as thermoplastic polyester, or saturated polyester.
Polyethylene Terephthalate/PET CAS:25038-59-9 Application
Polyethylene terephthalate has been widely used in plastic packaging bottles, films and synthetic fibers. Use At present, polyethylene terephthalate resin (polyester chip) is mainly used for bottle-grade polyester (widely used in the packaging of various beverages, especially carbonated beverages), polyester film (mainly used in packaging materials, film and tape, etc.) and polyester for chemical fibers.
