Description
Xylene is a colorless, flammable liquid hydrocarbon characterized by a sweet aromatic odor. It consists of three isomers: ortho-xylene, meta-xylene, and para-xylene, collectively referred to as mixed xylene. Known for its excellent solvency properties, xylene is widely used in various industrial and commercial applications.
In the paint and coatings industry, xylene serves as a solvent, enhancing the application and drying properties of products. It is also utilized in the production of adhesives, printing inks, and in the formulation of cleaning agents. As a chemical intermediate, xylene is essential in manufacturing key compounds like terephthalic acid, which is used to produce polyester fibers and resins.
