Polyethylene Terephthalate

Polyethylene Terephthalate:

Researchers have recently discovered a new deep-sea enzyme that can degrade Polyethylene Terephthalate (PET).

  • Polyethylene Terephthalate (PET) is the most commonly used thermoplastic polymer in the world.
  • It belongs to the family of polyesters.
  • PET is produced by the polymerization of ethylene glycol and terephthalic acid.
  • When heated together under the influence of chemical catalysts, ethylene glycol and terephthalic acid produce PET in the form of a molten, viscous mass that can be spun directly to fibres or solidified for later processing as plastic.
  • It is highly flexible, colorless and semi-crystalline resin in its natural state.
  • It shows good dimensional stability, resistance to impact, moisture, alcohols and solvents.
  • It exhibits excellent electrical insulating properties.
  • It is very lightweight, which reduces transportation costs.
  • It has good gas (oxygen, carbon dioxide) and moisture barrier properties.
  • It can be commercially recycled by thorough washing and re-melting, or by chemically breaking it down to its component materials to make new PET resin.
  • It is widely used for packaging foods and beverages, especially convenience-sized soft drinks, juices and water.
  • The polymer finds use in fabrics, and the textile industry.
  • It is also used in films to mold parts for automotive, electronics, etc.
