中文简体Dioctyl terephthalate (DOTP) is an organic compound with the molecular formula C24H38O4. It is a transparent oily liquid, insoluble in water, soluble in common organic solvents [1]. Dioctyl terephthalate is an excellent main plasticizer for polyvinyl chloride (PVC) plastics. Compared with the commonly used diisooctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, low volatility, anti-extraction, softness and good electrical insulation performance, and it shows excellent durability in products. Soap and water resistance and low temperature softness.
Dioctyl terephthalate (DOTP) is an excellent primary plasticizer for polyvinyl chloride (PVC) plastics. Compared with the commonly used diisooctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, low volatility, anti-extraction, softness and good electrical insulation performance, and it shows excellent durability in products. Soap and water resistance and low temperature softness. Because of its low volatility, the use of DOTP can fully meet the temperature resistance level requirements of wire and cable, and can be widely used in 70°C resistant cable materials (IEC standard of the International Electrotechnical Commission) and various other PVC soft products. In addition to being widely used as a plasticizer for cable materials and PVC, DOTP can also be used for the production of artificial leather films. In addition, it has excellent compatibility and can also be used as a plasticizer for acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose, etc. It can also be used as a plasticizer for synthetic rubber, a coating additive, a lubricant for precision instruments, a lubricant additive, and a softener for paper.
