Product Description

ApplicationIt is mostly used in the production of polyethylene terephthalate (polyester), which is an important raw material for polyester fiber, film, plastic products, insulating paint and plasticizer.

StorageStored in a dry and ventilated warehouse.



High-Quality Intermediate for Polyester Industry

Terephthalic acid serves as a crucial raw material in the manufacturing of polyethylene terephthalate (PET) resin and polyester fibers. Its high purity and stable nature under normal conditions make it a preferred choice for manufacturers seeking consistent performance and product quality.


Safe Handling and Storage

This substance is non-poisonous, non-self-igniting, and stable when kept in a cool, dry environment away from strong oxidizers and bases. Thanks to its negligible vapor pressure and non-hazardous classification, Terephthalic acid is easy and safe to store in standard industrial settings.


Versatile Industrial Applications

Beyond its primary use in PET and fiber production, Terephthalic acid is employed in the creation of resins, plasticizers, chemical fiber, coatings, and even in pharmaceuticals. Industrial users benefit from its effectiveness, reliability, and compatibility with a range of processes.

FAQ's of Terephthalic acid:


Q: How is Terephthalic acid commonly used in industry?

A: Terephthalic acid is primarily an intermediate in the production of polyethylene terephthalate (PET) resin and polyester fibers, but it is also used to manufacture plasticizers, coatings, resins, chemical fibers, and pharmaceuticals.

Q: What is the recommended storage condition for Terephthalic acid?

A: It should be stored in a cool, dry, and well-ventilated area, away from incompatible substances such as strong oxidizers and bases, to ensure stability and product longevity.

Q: When is Terephthalic acid considered hazardous?

A: Under the Globally Harmonized System (GHS), Terephthalic acid is not classified as hazardous, provided it is handled and stored according to standard industrial practices.

Q: Where is Terephthalic acid manufactured and exported from?

A: It is widely manufactured, exported, and supplied by chemical producers in China and distributed globally for industrial use.

Q: What benefit does Terephthalic acid offer for PET and polyester production?

A: Its high purity, strong acidity, and stability under normal conditions enable efficient, high-yield production of PET resins and polyester fibers with consistent material properties.

Q: How does the process of converting Terephthalic acid to PET resin work?

A: Terephthalic acid reacts with ethylene glycol in a condensation polymerization process, producing PET resin, which can then be formed into fibers, films, or containers.

Q: What precautions should be taken during the handling of Terephthalic acid?

A: Ensure good ventilation, avoid contact with incompatible materials, and handle the powder carefully to minimize dust. Always follow proper industrial hygiene practices during use.
