Widely used as plasticizers in polyvinyl chloride (PVC) and other polymers to improve flexibility, durability, and workability. Commonly found in flexible PVC applications such as cables, wires, flooring, films, and coatings. Also utilized in sealants, adhesives, and inks due to their good solvating properties and low volatility. Their extended alkyl chains contribute to improved migration resistance and low-temperature performance, making them suitable for outdoor and demanding environments. Additionally, used in some personal care products and lubricant formulations where mild plasticizing action and compatibility are required.
