Polyethylene terephthalate, commonly known as PET, is a thermoplastic polymer used mainly for the production of containers, textile fibers and industrial applications.
PET possesses properties that include high resistance, thermal stability and low gas permeability, making it a material valued for its versatility and durability.
Introduction to PET
Its characteristics make it suitable for manufacturing plastic bottles, food containers, medical equipment components, vehicle parts and many more products, but… What is needed?
PET production requires two main components:
- Purified terephthalic acid (PTA) or dimethyl terephthalate (DMT)
- Ethylene glycol (EG)
These elements react through a process known as condensation polymerization, both are essential for their chemical reaction.
The PET obtained after its polymerization can be molded to achieve the final product by methods such as injection molding, injection-blow and extrusion-blow.
However, raw materials are also crucial for manufacturing high-quality PET. Impurities in the inputs can adversely affect the mechanical and chemical properties of the polymer.
Factors affecting PET quality
The temperature and pressure used during and after production are crucial, as inadequate conditions can lead to incomplete polymerization or material malformations. To avoid this, it is recommended to store PET with controlled temperature and free of moisture.
The presence of contaminants either in the raw material or in the manufacturing environment can negatively affect PET quality, which is why it is essential to maintain a clean environment.
