PTA is one of the important commodity organic raw materials, widely used for chemical fiber, light industry, electronics, construction and other aspects of the national economy. At the same time, the application of PTA and more concentrated, more than 90% of the world's PTA for the production of polyethylene terephthalate (hereinafter referred to as polyester, PET). Producing one ton of PET need 0.85 0.86 0.33 0.34 tons of tons of PTA and MEG (ethylene glycol). Polyester including fiber slice, polyester fiber, bottle with biopsy and film. In the domestic market, 75% of the PTA for the production of polyester fiber; Used in the production of bottle grade polyester 20%, mainly used in a variety of drinks especially carbonated drinks packaging; 5% for membrane mainly polyester used in packaging materials, films and tapes. Visible, PTA downstream extension of the main products are polyester fiber.
