Used primarily as a plasticizer in polymers to enhance flexibility and durability. Commonly found in PVC products such as cables, flooring, and synthetic leather. Provides good low-temperature performance and resistance to heat and UV degradation. Also used in adhesives, sealants, and coatings to improve workability and adhesion. Due to its relatively low volatility, it helps maintain plastic properties over extended periods. Limited use in consumer products due to concerns over phthalate exposure, especially in toys and food-contact materials.
