Purified Terephthalic Acid (PTA) is a basic raw material for polyester. Purified Terephthalic Acid (PTA) reacts with Mono Ehtylene Glycol (MEG) to produce polyester. Purified Terephthalic Acid (PTA) is used to manufacture polyester coatings resins for use in the formulation of general metal, appliance, automotive, industrial maintenance, and coil coatings. The primary application for PTA is in combination with glycol in polyester powder coating resins. It has also been used in unsaturated polyesters for fiberglass-reinforced plastics applications. Polyethylene Terephthalic (PET) films, sheet and molded containers for food packaging continue to grow in popularity. Light weight soft drink containers based on Purified Terephthalic Acid (PTA) are crystal clear and shatter proof. In addition, blister packaging for fresh and prepared food products is often based on Purified Terephthalic Acid (PTA). The aromatic ring of PTA imparts excellent hardness and corrosion and stain resistance to coatings resins and unsaturated polyesters. PTA has moderate solubility in molten glycols which can increase synthesis times, and it imparts moderate solubility to resins. Additionally, Purified Terephthalic Acid (PTA) is used by the military in production of smoke munitions. All buyers are responsible for proper usage and application of this product.
