Terephthalic Acid CAS 100-21-0
Sinochem is a major Purified Terephthalic Acid & PTA supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Purified Terephthalic Acid & PTA.
Purified Terephthalic acid is mainly used as a precursor for polyester fiber PET, which is used to make clothing and plastic bottles. Terephthalic acid is produced in millions of tons per year. It is one of the three phthalic acid isomers.
- High Purity: PTA is highly purified, ensuring minimal contaminants and better performance in downstream applications.
- Versatile Applications: Used primarily in the production of polyester fibers, resins, and films, contributing to a wide range of industries such as textiles, packaging, and automotive.
- Excellent Chemical Stability: PTA is stable under normal industrial conditions, making it ideal for manufacturing durable products.

Properties: Terephthalic acid is an important aromatic dicarboxylic acid with good chemical stability and high melting point. PTA has weak acidity and is soluble in hot water but has low solubility in cold water. Its chemical properties are relatively stable and it is not easy to react chemically at room temperature, but it can be oxidized at high temperature or react with alkaline substances to form corresponding salts.
Package: Plastic bags with cloth bags or polypropylene woven bags are used for packaging, each bag is 20kg.
Storage: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Store separately from oxidants and alkalis and do not store them together. Equip with appropriate types and quantities of fire-fighting equipment. The storage area should be equipped with appropriate materials to contain leaks.
Safety Protection: It is not as irritating to the skin as phthalic acid, and it does not cause allergies. Allergic symptoms, wheezing, ulcers, etc. that occur during the production process are caused by impurities in the raw materials, which can also be decomposed and detoxified in the organism like phthalic acid. For those with allergies, contact with this product may cause rashes or bronchial asthma or bronchitis. It is advisable to wear a dust mask during operation.
About Us: With over many years as a certified Purified Terephthalic Acid & PTA manufacturer, we combine innovation with stringent production standards to deliver high-performance product.

Benzene-1,4-dicarboxylic acid Applications
1. Manufacturing polyester plastics: One of the most famous uses of PTA is as a raw material for polyester plastics (especially PET).
2. Fiber production: PTA, as a key raw material for the production of polyester fibers, plays an important role in the textile industry.
3. Plasticizers: PTA can also be used to synthesize certain types of plasticizers, which are used to improve the flexibility and plasticity of plastics, making them more flexible and versatile in applications in different fields.
4. Coatings and resins: In the chemical industry, PTA is also used as a raw material for the manufacture of coatings and resins. It can improve the durability and chemical resistance of the coating, so it is widely used in surface treatment in the fields of automobiles, construction, and home appliances.
5. Other uses: PTA is also used as an intermediate for the manufacture of certain medicines and chemical reagents, or as a basic substance for some advanced chemical syntheses.
