Used primarily as a plasticizer in polymers to improve flexibility and durability, especially in coatings, adhesives, and resin formulations. Offers good solvency and low volatility, making it suitable for applications requiring long-term performance under moderate heat and light exposure. Commonly found in cellulose-based plastics and synthetic rubber compounds to enhance processability and final product resilience. Also utilized in some printing inks and sealants due to its compatibility with aromatic and chlorinated solvents.
