Dioctyl terephthalate #CAS6422-86-2
Dioctyl terephthalate (DOTP) is a high-performance primary plasticizer for polyvinyl chloride (PVC) plastics. Compared with the commonly used diisooctyl phthalate (DOP), it has advantages such as heat resistance, cold resistance, low volatility, pull-out resistance, flexibility, and good electrical insulation properties. In chemical book products, it exhibits excellent durability, soap water resistance, and low-temperature flexibility. Due to its low volatility, DOTP can fully meet the temperature resistance requirements of wires and cables and can be widely used in 70°C resistant cable materials (International Electrotechnical Commission IEC standard) and various other flexible PVC products.
Application of Dioctyl terephthalate
It is used primarily as a plasticizer for polyvinyl chloride and other polymers.DOTP can form a composite blend with polyaniline (PANI)-ethyene dimethacrylate (EDMA), which can be used in the fabrication of conductive films. It may also be used as a plasticizer with polyvinyl chloride (PVC) to form solutions for artificial intravessel plaque.
