Widely used as a plasticizer, it enhances the flexibility and workability of rigid polymers, especially polyvinyl chloride (PVC). It is commonly found in products such as cables, flooring, hoses, and medical tubing due to its ability to improve durability and elasticity. It has also been used in adhesives, sealants, and coatings to extend flexibility and adhesion. Due to health and environmental concerns, its use is increasingly restricted in consumer products, particularly in children's items and applications involving direct human contact.
