(1). high purity ethylene terephthalate and ethylene glycol were obtained by the condensation polymerization of polyethylene terephthalate.
(2). Purified Terephthalic Acid can also with 1,4-butanediol or 1,4-cyclohexane dicarboxylic acid reaction generated corresponding esters (such esters, mainly used in the production of polyester, and polyester is the main raw material for the production of polyester fiber (polyester), and polyester fiber is the main varieties of synthetic fiber), polyester and used for manufacturing special materials such as bulletproof vests, safety belt, tire cord, fishing net, rope, cloth and insulating materials.
(3). Purified Terephthalic Acid can also produce bottle grade PET, such as a variety of beverage packaging, especially the packaging of carbonated drinks, etc..
(4). there is also a small portion for the production of film grade polyester, such as should be used for packaging materials, film and tape, etc..
(5).Purified Terephthalic Acid downstream extension of the product is mainly polyester fiber and plasticize (to promote the formation of plastic film).
