PTA is one of the important bulk organic raw materials, widely used in chemical fiber, light industry, electronics, construction and other aspects of the national economy. At the same time, the application of PTA is more concentrated. More than 90% of PTA in the world is used to produce polyethylene terephthalate (PET). It needs 0.85-0.86 tons of PTA and 0.33-0.34 tons of MEG to produce 1 ton of pet. Polyester includes fiber chip, polyester fiber, bottle chip and film chip. In the domestic market, 75% of PTA is used in the production of polyester fiber; 20% is used in the production of bottle grade polyester, mainly used in the packaging of various drinks, especially carbonated drinks; 5% is used in film grade polyester, mainly used in packaging materials, films and tapes. It can be seen that the downstream extension product of PTA is mainly polyester fiber.
