  • Applications

    Di-(2-ethylhexyl) terephthalate (CAS 6422-86-2) is primarily used as a plasticizer for polyvinyl chloride (PVC) and other polymers, improving flexibility and processability in consumer plastics, films, and packaging. It is often evaluated as a phthalate alternative in PVC formulations. It is also used in coatings and inks for flexible films and laminates to impart durability and elongation. In adhesives and sealants, it serves as a plasticizing agent to enhance flexibility and cure characteristics. It finds applications in automotive interior materials such as PVC-based components and in cable insulation and other electrical/electronic components requiring flexible, durable formulations. Overall, it supports a range of polymer formulations across packaging, coatings, adhesives, and electronics.
