Purified Terephthalic Acid is major raw materiel for making polyester polymer driven by increasing end usages of Polyesters in apparel, packaging and industrial applications.
PTA was first introduced in 1965 as an alternative to Dimethyl Terephthalate (DMT) for the production of polyester. By the end of 2004, almost 90% of all polyester was made with PTA and this trend is continuing.
Today, polyester is applied in all walks of life, producing clothing, furniture, upholstery, containers and films. It is also used as an intermediate material for the production of pesticides, inks and paint products.
