          PET
        Polyethylene terephthalate chemical formula-[OCH2-CH2OCOC6H4CO]-English name: polyethylene terephthalate, PET for short, is a high polymer, comes from terephthalate condensation reaction of dehydration.  Terephthalate is obtained from esterification of Terephthalic acid and ethylene glycol. PET are creamy white or pale yellow, highly crystalline polymers, surface smooth and bright. Over a wide temperature range with excellent physical and mechanical properties, long-term service temperature up to 120 ℃, excellent electrical insulation, even under high temperature and high frequency, its performance is still good, but poor Corona-resistant and creep resistance, fatigue resistance, friction resistance, dimensional stability is good.   
          Advantage PET as a packaging material:
        ① has good mechanical properties, impact strength is 3~5 times the other films, good folding resistance.   
        ② oil and fat resistant, resistant to diluted acids, alkali, resistant to most solvents.   
        ③ has excellent resistance to high and low temperature performance, at 120 ° c temperature range for long-term use, short-term use 150 ℃ high temperature resistance, may be resistant to-70 ℃ at low temperature, and high and low temperature had little effect on the mechanical properties.   
        ④ gases and water vapor permeability is low, both excellent resistance performance of gas, water, oil, and the smell.   
        ⑤ transparent, UV, gloss, good.   
        ⑥ no poison, no smell, health safety, and can be directly applied to food packaging.   
          1.1 history of PET
        In 1941, was the first United Kingdom J. tt. Whinfield and J. T. Dickon developed. PET as fiber raw material has a history of 53 years, United Kingdom Imperial Chemical industries (1. c.  I) in 1946 as a pet (Teleron) fibers go into production, then United States DuPont (Dupent) in 1948 with "Chun-LUN" (Dacron) fiber production. PET classified and non-fiber grade polyester chips fiber grade pet chip. ① fiber grade polyester used in the manufacture of polyester staple fiber and polyester filaments, are supplied polyester fiber processing fibers and related products, raw materials, polyester fiber production the greatest variety. ② non-fiber grade polyester bottles, films and other uses, widely used in packaging, electronics, health care, construction, automobile and other fields, in which packaging is the biggest non-polyester fibre application markets, but also the fastest growing PET segment.   
          1.2 classification and uses
        PET raw material for ethylene glycol (EG) and purified Terephthalic acid (PTA) much used as a fiber can be divided into two major categories of non-engineering plastics-and engineering-level.   
        PET has excellent properties (heat resistance, chemical resistance. Strong toughness, electric insulation, security, etc), the price is cheap, so widely used as fibers, films and plastics, polyester bottle and so on. International polyester thermoplastic industrial products have the following 6 areas (already formed industrial products sold).   
          (1)
          (2) polyethylene terephthalate glycol (PBT)
          (3) the poly naphthalene dicarboxylic acid glycol ester (PEN)
          (4) polyethylene terephthalate engineering grade PET
          (5) polyethylene terephthalate standard grade PET
          (6) polyethylene terephthalate recycle-grade PET (including blends and 100% recycling)
        Non-plastic one primarily for fibers, beverage bottles, films, sheets, bake food containers.   
        Engineering grade PET organic solvent resistance, good weatherability. Disadvantage is the slow crystallization rate, processing difficulties, high molding temperature, long production period, the impact of poor performance. Generally strengthening, filling, mixing and other methods to improve their processing and properties of glass fiber reinforcing effect and improve rigidity and heat resistance of resin, drug resistance, electrical properties and weatherability. Add a nucleating agent and a crystallization accelerant means improved slow crystallization speed of shortcomings. Can be improved by adding flame retardant and flame drops agent PET flame-retardant and self-extinguishing.   
        In addition, the performance improvement of PET, PET category and elastic body, PBT, PC, PS, ABS, PA to form alloys.   
        PET (enhanced PET) is taken by injection moulding process, other methods include extrusion, blow molding, coating, sealing and welding, machining, vacuum coating and other secondary processing methods. Must be fully dry before. Main application for electronic electrical aspects has: electrical socket, and electronic connection device, and rice cooker put hand, and TV bias yoke, Terminal Taiwan, broken electrical shell, and switch, and motor fan shell, and instrument mechanical parts, and cash registers parts, and irons, and electromagnetic stove oven of accessories; car industrial in the of flow control valve, and carburetor cover, and Windows controller, and pedal transmission, and distribution disc cover; mechanical industrial gear, and leaves, and belt round, and pump parts, and addition also has wheelchair body and the wheels, and Lampshade shell, and lighting device shell, and drain joints, and zipper, and Clock parts, and so on.
