Di-tert-butyl decanedioate is widely used as a plasticizer in the production of polymers and resins. It enhances the flexibility, durability, and workability of materials such as PVC, polyurethanes, and synthetic rubbers, making it valuable in manufacturing processes. Additionally, it serves as an intermediate in organic synthesis, particularly in the creation of specialty chemicals and coatings. Its application extends to the formulation of adhesives and sealants, where it improves performance and longevity. In the automotive and construction industries, it contributes to the development of high-performance materials that withstand harsh environmental conditions.
