Dioctyl Terephthalate (DOA)

Dioctyl Terephthalate (DOA) is a versatile plasticizer widely used to improve the flexibility, durability, and processability of polymer systems. Known for its low-temperature performance, resistance to migration, and long-term stability, DOA is particularly valuable in polyvinyl chloride (PVC) applications that demand flexibility under extreme conditions. It is extensively used in wire and cable insulation, automotive interiors, flooring, films, and coated fabrics, where it delivers softness, resilience, and enhanced service life.

Outside of PVC, DOA finds application in adhesives, sealants, and specialty coatings, where it enhances formulation stability and flow. Its excellent cold-weather properties make it ideal for outdoor and cold-climate products, as well as flexible packaging and consumer goods. With its balance of efficiency, weather resistance, and broad polymer compatibility, Dioctyl Terephthalate remains an essential plasticizer across industries such as automotive, construction, electrical, packaging, and specialty chemical manufacturing.
