The product has the outstanding performances of electrical resistance, heat resistance, low-temperature volatility, low glass transition temperature, low volatility and the like, and is an ideal plasticizer for producing excellent cable materials. Dioctyl terephthalate (DOTP) molecular formula: C24H3804 is a good primary plasticizer for polyvinyl chloride (PVC) plastics. Compared with the currently common dioctyl terephthalate (DOP), the high-temperature-resistant and low-temperature-resistant dioctyl terephthalate has the advantages of heat resistance, cold resistance, difficult volatilization, extraction resistance, good flexibility, good electrical insulation performance and the like, and shows excellent durability, soap water resistance and low-temperature flexibility in products. Because of low volatility, DOTP can completely meet the requirement of temperature resistance grade of wires and cables, and can be widely applied to 70 ℃ resistant cable materials (International electrotechnical Commission IEC standard) and other various PVC soft products. The DOTP can be used for producing artificial leather films besides a large amount of plasticizers used for cable materials and PVC. In addition, the plasticizer has excellent compatibility, and can be used for plasticizers such as acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, and cellulose nitrate. It can also be used as plasticizer, coating additive, lubricant for precision instruments, lubricant additive for synthetic rubber, and softener for paper.

But traditional device to thick dioctyl terephthalate stir is structural comparatively simple, and the function singleness only stirs through the stirring rod in raw materials inside, and efficiency is not high to the effect of stirring is not fully satisfactory yet, and the practicality is not strong when in-service use.
