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 resilience. Also employed in sealants, coatings, and synthetic leather to increase softness and elongation. Historically used in consumer products like shower curtains and faux finishes, though its use has declined in some regions due to health and environmental concerns. May be present in some industrial applications where resistance to aging and low-temperature performance are required.
