Technical Document

 

BRIEF OVERVIEW

purified terephthalic acid (PTA) is a raw material which is used in the production of high-performance multipurpose plastics like polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT) and even forms of bioplastics. It also finds its vast usage in the production of polyester fibers in the global market. They are used to manufacture polyester coating resins for manufacturing general metal, appliances, automotive, industrial maintenance even coil coatings.


MANUFACTURING PROCESS

At first step of production process, Crude Terephthalic Acid (CTA) is produced through catalytic liquification and oxidation among air, paraxylene (as main raw material) and acetic acid (as solvent) and then the CTA is hydrogenated to remove the impurities and then is separated and dried to produce fibre grade PTA.
