Didecyl adipate is widely used as a plasticizer in the production of flexible PVC products, enhancing their durability and elasticity. It is particularly valued in applications requiring low-temperature flexibility, such as cables, hoses, and synthetic leather. Additionally, it serves as a lubricant in various industrial processes, reducing friction and improving efficiency. Its compatibility with other polymers also makes it suitable for use in adhesives, coatings, and sealants, providing improved performance and longevity. In personal care products, it acts as an emollient, offering a smooth texture and enhancing the spreadability of formulations like lotions and creams.
