Introduction:

PTA widely used in chemical fibers, light industry, electronics, construction and  all aspects of the civil economy,PTA is one of the important bulk organic raw materials.  At the same time, the application of PTA is concentrated, more than 90% of PTA in the world is used in the production of polyethylene terephthalate (PET). It takes 0.85-0.86ton PTA to produce 1 ton PET and 0.33-0.34 ton of MEG (ethylene glycol). Polyesters include fiber chips, polyester fibers, bottles slices and film sections. In the domestic market, 75% of PTA is used to produce polyester fibers and 20% is used to produce bottle grade polyester, which is mainly used in the packaging of various beverages, especially carbonated beverages; 5% for membrane grade polyester, mainly applied to packaging materials, film and tape.
