PTA is an important organic raw material, widely used in the chemical fibre industry, the light industry, the electronics industry and the construction industry and some other fields. Over 90 percent of the world's PTA is used to produce PET. Producing 1 ton of PET needs 0.85-0.86 ton of PTA and 0.33-0.34 ton of MEG. Meanwhile, in China's Domestic market, about 75% of PTA is used to make polyester fibre, 20% to make bottle-grade polyester, which is mainly used in packing beverages, especially sodas, and 5% to make film-grade polyester, with the associated products used as packaging material, films and magnetic tapes.
