Butyl cyclohexyl phthalate is primarily used as a plasticizer in the manufacturing of flexible polyvinyl chloride (PVC) products. It enhances the flexibility, durability, and workability of PVC materials, making it suitable for applications such as vinyl flooring, wire and cable insulation, and synthetic leather. Additionally, it is employed in the production of adhesives and sealants, where it improves the material's adhesive properties and resistance to environmental factors. Its compatibility with various polymers also makes it a valuable component in coatings and inks, providing enhanced performance and stability.
