Polyethylene terephthalate(PET) is a general-purpose plastic made through polycondensation of PTA with ethylene glycol (EG). This material has many outstanding properties: resistance to both heat and cold, transparency, electrical qualities, chemical proof and abrasion proof; For all these reasons, it is finding a wide variety of applications in the fibers, PET bottle and films. We have own licenses for an polycondensation process for producing polyethylene terephthalate(PET).

Process characteristics

Our polyethylene terephthalate(PET) process technology achieves polycondensation reactions at low temperatures by using esterificaltion in our proprietary, efficiently-heated equipment, and the mixing equipment for highly viscous fluids that have been one of our specialties for many years.This process results in the following properties.

  1. Production of polyethylene terephthalate(PET) with little diethylene glycol as a byproduct.
  2. Production of polyethylene terephthalate(PET) with little color adherence.
  3. Possible to construct large scale plant

Since 1965 we have completed over 100 plants.
Along with licensing, we provide a full range of services based on these licenses, including engineering, design, manufacturing, procurement, construction and commissioning. Regarding the scope of work, we take a flexible approach based on customers' needs.
