Used primarily as a plasticizer in polymers to enhance flexibility and durability. Commonly found in vinyl flooring, wall coverings, and adhesives due to its ability to improve workability and longevity. Also employed in sealants and coatings where resistance to aging and environmental stress is required. Its solvency properties make it useful in some printing inks and resins. Has been used in small amounts in consumer products like synthetic leather and rubber goods. Due to health and environmental concerns, its use has declined in recent years, especially in products intended for children or indoor environments.
