Dioctyl dodecanedioate 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 in automotive parts, cables, and hoses. Additionally, it serves as a lubricant in various industrial processes, reducing friction and improving the efficiency of machinery. Its compatibility with other polymers also makes it suitable for use in coatings and adhesives, providing improved performance and stability. In personal care products, it acts as an emollient, offering a smooth texture and enhancing the spreadability of creams and lotions.
