| Purified Terephthalic Acid (“PTA”) is our core product of our
main business. It is the principal raw material mainly used
for:
(1) The Polyester Industry to produce fibers and yarns,which later will be used for textile products, and for
(2) The PET (Polyethylene Terephthalate) Industry
to produce bottles, microwave utensils, x-ray and photographic film, containers, and certain products used in the automobile industry, such as car parts and roof linings and hygiene industries, such as diapers and sanitary napkins.

Therefore, PTA is one of key petrochemical materials as intermediate product to be
used to produce products as our necessity of daily life.With no exception than most
of the hydrocarbon chemicals, it finds their origin from crude oil, natural gas, etc. The
major raw material to produce PTA is Para-Xylene (PX), an aromatic chemical derived
through crude oil.
In terms of product packing, we sell our PTA to local market by bulk trailer and export our PTA to overseas market with jumbo bag, or sea bag.
The following diagram illustrates where PTA and its principal feedstock, paraxylene,
fit in the polyester production chain.
