How polyethylene terephthalate (PET) is made?

Polyethylene terephthalate (PET) is synthesized through a two-stage polycondensation process involving the following key components:


Purified terephthalic acid (PTA): This is the primary source of the aromatic ring structure in PET.
Ethylene glycol (EG): This diol acts as the linking agent between the terephthalate units.


Esterification or Transesterification: The first stage involves the reaction between PTA and EG. Traditionally, esterification with water as a byproduct occurs. However, transesterification with dimethyl terephthalate (DMT) and methanol as a byproduct is becoming more common due to its efficiency.
Polycondensation: In the presence of a catalyst (often antimony or titanium compounds), the remaining hydroxyl groups on EG react with the carboxylic acid groups on PTA or DMT, eliminating water or methanol and forming an ester linkage. This chain-growth reaction continues, building high-molecular-weight PET molecules.

Uses of PET - Polyethylene Terephthalate

Manufacturers and researchers in the industrial sector keep coming up with new ideas for using PET - Polyethylene Terephthalate. At present, this organic compound is used as:
  • Packaging: PET is widely used in packaging applications due to its excellent barrier properties, clarity, and lightweight nature. It is commonly used for packaging water bottles, soft drinks, juices, food containers, and personal care products.
  • Textiles: PET can be processed into fibers for use in textiles. Polyester fibers made from PET are used in clothing, home furnishings, carpets, and industrial applications like ropes and conveyor belts.
  • Engineering Plastics: PET can be reinforced with glass fibers or other additives to create engineering plastics with enhanced mechanical properties. These plastics are used in automotive components, electrical components, and industrial machinery.
  • Films: PET films are used in a wide range of applications including packaging, labels, graphic arts, and electrical insulation. They offer excellent mechanical properties, optical clarity, and barrier properties.
  • Medical Applications: PET is used in the medical industry for products like PET bottles for pharmaceuticals and medical devices due to its inertness, transparency, and ability to be sterilized.
  • 3D Printing: PET is used as a filament in 3D printing due to its strength, flexibility, and ease of printing.
  • Solar Panels: PET films are used as the backing material for photovoltaic solar panels due to their durability and transparency to allow sunlight to reach the solar cells.
  • Geotextiles: PET fibers are used in geotextiles for applications such as soil stabilization, erosion control, and drainage due to their strength and durability.
