Applications of PTA

Polyester: - Purified Terephthalic Acid (PTA) is a basic raw material for polyester. Purified Terephthalic Acid (PTA) reacts with Mono Ehtylene Glycol (MEG) to produce polyester.

  1. Textiles: Purified Terephthalic Acid (PTA) derivative, Polyester, is the largest synthetic fibre used in textiles.

  2. Packaging: Polyethylene Terephthalic (PET) films, sheet and molded containers for food packaging continue to grow in popularity. Light weight soft drink containers based on Purified Terephthalic Acid (PTA) are crystal clear and shatter proof. In addition, blister packaging for fresh and prepared food products is often based on Purified Terephthalic Acid (PTA).

  3. Furnishing: Staple fiber made for polyester is also used in furniture application like cushions, upholstery etc.

  4. Consumer Goods: Apart from textiles, furnishing as detailed above, PET is used in films for audio and video recording tapes.

Coatings: - Purified Terephthalic Acid (PTA) is used in the polyester component of environmentally compliant coating resins, including water soluble and powder systems.

Resins: - Purified Terephthalic Acid (PTA) also finds applications in Unsaturated Polyester which are used as engineering plastics.

Purified Terephthalic Acid (PTA) has also applications in Speciality Chemical Industries.
