Terephthalic acid is an organic compound with formula C 6 H 4 (CO 2 H) 2. This white solid is a commodity chemical, used principally as a precursor to the polyester PET, used to make clothing and plastic bottles. Several million tons are produced annually. [3] .

2023年5月31日 · PTA是重要的大宗有机原料之一，广泛用于与化学纤维、轻工、电子、建筑等国民经济的各个方面。 同时，PTA的应用又比较集中，世界上90%以上的PTA用于生产聚对苯二甲酸乙二醇酯 (简称聚酯，PET)。 生产1吨PET需要0.85－0.86吨的PTA和0.33-0.34吨的MEG（乙二醇）。 聚酯包括纤维切片、聚酯纤维、瓶用切片和薄膜切片。 国内市场中，有75％的PTA用于生产聚酯纤维；20％用于生产瓶级聚酯，主要应用于各种饮料尤其是碳酸饮料的包装；5％用于膜 …

Purified Terephthalic Acid (PTA) is an organic compound that is the main raw material for polyethylene terephthalate (PET) and for polyester fibers. PET is widely used in today’s consumer goods and goods packaging and is found in everything from plastic water bottles and food containers to clothing, home furnishings, and automotive production.

PTA is primarily used to produce polyester fibers and yarn. It is also used to manufacture plasticizers, liquid crystal polymers, and polybutylene terephthalate.

Eastman™ Purified Terephthalic Acid (PTA) is used to manufacture polyester coatings resins for use in the formulation of general metal, appliance, automotive, industrial maintenance, and coil coatings. The primary application for PTA is in combination with Eastman NPG™ Glycol in polyester powder coating resins.

PTA is predominantly used as a raw material in manufacture of Polyester Staple Fibres, Polyester Filament Yarns and Polyethylene Terepthalate in conjunction with Mono Ethylene Glycol (MEG). Polyester Fibres/Yarns find application in the production of textiles and films. PTA also finds use in small quantities in the manufacture of paints, etc.

Uses of PTA (Terephthalic acid) Polyester fibers based on PTA both alone and in blends with natural and other synthetic fibers. Polyester films based on PTA are used in audio and video recording tapes, data storage tapes, photographic films, labels and other sheet material.

Alpek Polyester is the largest producer of Purified Terephthalic Acid (PTA) in the Americas and is one of the largest producers globally. PTA is an organic compound that is the main raw material used for production of polyethylene terephthalate (PET) in the form of PET Resins , PET Sheet and Polyester fibers.

Purified Terephthalic Acid (PTA) is a colorless crystalline solid that plays a pivotal role in the chemical industry. It is primarily used as a raw material for the production of polyesters, which are widely used in various applications, including textiles, packaging, and engineering plastics.

Purified Terephthalic Acid (PTA) is an organic compound with formula C 6 H 4 (CO 2 H) 2. The main raw material for polyethylene terephthalate (PET) and polyester fibers is produced by oxidizing paraxylene. Polyester fibers are used mainly in rugs, clothing, furniture and industrial applications, as well as other consumer products. Application :
