Purified Terephthalic Acid Introduce
Purified Terephthalic Acid (as known as PTA with CAS: 100-21-0) 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 relatively concentrated. More than 90% of PTA in the world is used to produce polyethylene terephthalate (PET). Production of 1 ton of PET requires 0.85-0.86 tons of PTA and 0.33-0.34 tons of MEG (ethylene glycol). Polyester includes fiber chips, polyester fibers, bottle chips and film chips. In the domestic market, 75% of PTA is used to produce polyester fiber; 20% is used for the production of bottle-grade polyester, mainly used for the packaging of various drinks, especially carbonated drinks; 5% is used for film-grade polyester, mainly used for packaging materials, films and tapes. It can be seen that the downstream extension products of PTA are mainly polyester fibers.
