Purified Terephthalic Acid (PTA)


Purified Terephthalic Acid (PTA)

What is Purified Terephthalic Acid (PTA)?

  It is pet raw material which is used in the production of high-performance multipurpose plastics like polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT) and even forms of bioplastics.

  When we want to know polyester films price and trend,we always need to check the price of PTA,Becuase PTA :Purified Terephthalic Acid ,is a very important polyester film raw material.Nearly all PTA is consumed in polyester production including polyester fibre, polyethylene terephthalate (PET) bottle resin and polyester film.

  It also finds its vast usage in the production of polyester fibers in the global market. They are used to manufacture polyester coating resins for manufacturing general metal, appliances, automotive, industrial maintenance even coil coatings.


   Terephthalic acid is an organic compound with formula C6H4(CO2H)2. This white solid is a commodity chemical, used principally as a precursor to the polyester PET, used to make clothing and plastic bottles.
