Dimethyl terephthalate (DMT) is a colorless to slightly yellowish crystalline acid with a molar mass of about 194.19 g/mol. It is a readily soluble substance in organic solvents such as methanol and acetic acid. At room temperature, DMT is a solid with a melting point of about 142-144°C. This chemical compound is characterized by its high purity and stability, making it an important raw material in various industries.

Applications of Dimethyl Terephthalate

One of the main applications of dimethyl terephthalate lies in the production of polyethylene terephthalate (PET). DMT serves as a precursor in the polycondensation reaction with ethylene glycol to form PET polymers. These PET polymers are widely used in the manufacturing of beverage bottles, food packaging, textile fibers, and other plastic products.

DMT is also used in the production of polyester fibers. Through polycondensation with diols, polyester polymers are formed, which are then spun into fibers. These polyester fibers are used in the textile industry for the production of clothing, home textiles, carpets, and technical textiles due to their high strength, dimensional stability, and ease of care.

In the coatings and paints industry, dimethyl terephthalate is used as a plasticizer and resin component. It enhances the flexibility, adhesion, and chemical resistance of paint films. DMT-based coatings are used in applications such as automotive bodies, metal and wood surfaces, furniture, and packaging.In the paint and coatings industry, Dimethyl Terephthalate is used as a plasticizer and resin component.

DMT is also utilized in the synthesis of plasticizers, especially phthalate plasticizers. These plasticizers are used in plastics, elastomers, coatings, and other materials to improve their flexibility and processability. They are used in products such as PVC pipes, cable sheathing, artificial leather, and flooring.

Dimethyl terephthalate (DMT) is an extremely versatile chemical raw material with a wide range of applications. From the production of PET and polyester fibers to the coatings and plasticizer industries, the outstanding properties of DMT make it an indispensable component of many everyday products. MCC is offering DMT also in a pure recycled form (r-DMT).
