Applications Mainly used for polyester, polyester resin, moisture absorbent, plasticizer, surfactant, synthetic fibers, cosmetics and explosives, and as a solvent for dyes/inks, to prepare engine antifreeze agent, gas dehydrating agent, manufacturing resin, and wetting agent for cellophane, fibre, leather and adhesives. It can produce synthetic resin PET. Fiber grade PET is polyester fiber. Bottle grade PET is used to make mineral water bottles. It can also produce aldehyde resin, glyoxal, and also be used as antifreeze. In addition to antifreeze used for automobiles, it is also used for industrial refrigeration transport, commonly referred to as refrigerant carrier.
