  2. Polyethylene terephthalate - Wikipedia

    en.wikipedia.org/wiki/Polyethylene_terephthalate

    Polyethylene terephthalate is produced largely from purified terephthalic acid (PTA), as well as to a lesser extent from (mono-)ethylene glycol (MEG) and dimethyl terephthalate (DMT). [41] [5] As of 2022, ethylene glycol is made from ethene found in natural gas, while terephthalic acid comes from p-xylene made from crude oil.

  3. PET bottle recycling - Wikipedia

    en.wikipedia.org/wiki/PET_bottle_recycling

    Polyethylene Terephthalate is one of the most common polymers in its polyester family. Its global market size was estimated to be worth 37.25 billion USD in 2021. [ 1 ] Polyethylene terephthalate is used in several applications such as; textile fibres, bottles, rigid/flexible packaging, and electronics.

  4. Polyester - Wikipedia

    en.wikipedia.org/wiki/Polyester

    With 18% market share of all plastic materials produced, it ranges third after polyethylene (33.5%) and polypropylene (19.5%) and is counted as commodity plastic. There are several reasons for the importance of polyethylene terephthalate: The relatively easy accessible raw materials PTA or DMT and MEG

  5. Two-liter bottle - Wikipedia

    en.wikipedia.org/wiki/Two-liter_bottle

    PepsiCo introduced the first two-liter sized soft drink bottle in 1970. [1] Motivated by market research conducted by new marketing vice president John Sculley (who would later be known for heading Apple Inc. from 1983 to 1993), [2] the bottle and the method of its production were designed by a team led by Nathaniel Wyeth of DuPont, who received the patent in 1973. [3]

  6. Polyethylene - Wikipedia

    en.wikipedia.org/wiki/Polyethylene

    Polyethylene was first synthesized by the German chemist Hans von Pechmann, who prepared it by accident in 1898 while investigating diazomethane. [12] [a] [13] [b] When his colleagues Eugen Bamberger and Friedrich Tschirner characterized the white, waxy substance that he had created, they recognized that it contained long −CH 2 − chains and termed it polymethylene.

  7. BoPET - Wikipedia

    en.wikipedia.org/wiki/BoPET

    BoPET (biaxially oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, [1] chemical stability, [1] dimensional stability, [2] transparency [1] reflectivity, and electrical insulation. [1] When metallized, it has [3] gas and moisture barrier ...

  8. List of synthetic polymers - Wikipedia

    en.wikipedia.org/wiki/List_of_synthetic_polymers

    The plastic kits and covers are mostly made of synthetic polymers like polythene, and tires are manufactured from polybutadienes. [1] However, due to the environmental issues created by these synthetic polymers which are mostly non-biodegradable and often synthesized from petroleum, alternatives like bioplastics are also being considered.

  9. Phthalates - Wikipedia

    en.wikipedia.org/wiki/Phthalates

    The terephthalate polymer PETE and the phthalate ester plasticizers are chemically different substances. [83] Despite this, however, many studies have found phthalates, such as DEHP in bottled water and soda. [84] One hypothesis is that these may have been introduced during plastic recycling. [84]
