Purified Terephthalic Acid (PTA) 

When people want to know PET films price and trend,they always need to check the price of PTA,

Because  PTA,full name :Purified Terephthalic Acid  is a very important raw material to make polyethylene terephthalate (PET),

Nearly all PTA is consumed in polyester production including polyester fibre, polyethylene terephthalate (PET) bottle resin and polyester film.

What is Purified Terephthalic Acid (PTA)?

It is a 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.

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.

History

The first unit for producing PTA was set up in 1961 and the second one was set up in 1991. However, the production of this resin was already pre-planned in the year 1967 when Amoco Chemicals Belgium was established.

Properties

PTA is majorly used as a prominent raw material for producing a variety of thermoplastics.  It has unique features which enhance its ability to be used as a raw material. These properties include:

• Excellent weathering
• Resistance towards chemicals & stains
• Hard & Flexible
• Good glass transition temperature range
• Efficient powder flow & fluidizing characteristics.
