Used primarily as a plasticizer in polymers, especially in PVC and other vinyl resins, to improve flexibility, workability, and durability. It is favored in low-temperature applications due to its good cold resistance, maintaining flexibility even under freezing conditions. Commonly found in automotive parts, wire and cable coatings, flooring, and synthetic leather. Exhibits good compatibility with other plasticizers and additives, enhancing processing stability. Also used in adhesives and sealants to improve tack and elongation properties. Its relatively low volatility helps maintain long-term performance in flexible plastic products.
