Used primarily as a plasticizer in polymer formulations, this compound enhances flexibility and workability of plastics, especially in polyvinyl chloride (PVC) and related resins. It improves low-temperature performance, maintaining material pliability under cold conditions. Its molecular structure supports good compatibility with polar polymers, leading to uniform dispersion and reduced migration over time. Commonly found in flexible films, cables, coatings, and automotive parts where durability and resistance to extraction are required. Also utilized in some adhesive and sealant formulations to improve elongation and stress resistance.
