Didodecyl benzene-1,4-dicarboxylate is widely used as a plasticizer in the polymer industry. It enhances the flexibility and workability of plastics, particularly in PVC products, by reducing brittleness and improving durability. This chemical is also employed in the production of adhesives and coatings, where it contributes to better film formation and adhesion properties. Additionally, it finds application in lubricants and greases, where it acts as a viscosity modifier, ensuring smoother performance and reduced friction in mechanical systems. Its stability under various conditions makes it suitable for use in high-temperature applications and industrial processes.
