Dioctyl terephthalate (DOTP) is an organic compound with the formula C24H38O4. It is a transparent oily liquid, insoluble in water, soluble in general organic solvents. 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, volatilization resistance, extraction resistance, softness and electrical insulation, etc. It shows excellent durability, soap resistance and water resistance and low softness and softness in the products.
Product performance
Dioctyl terephthalate (DOTP) is a good main plasticizer for polyvinyl chloride (PVC). Compared with the commonly used diisooctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, volatilization resistance, extraction resistance, softness and electrical insulation, etc. It shows excellent durability, soap resistance and water resistance and low softness and softness in the products. Because of its low volatility, the use of DOTP can fully meet the requirements of wire and cable temperature resistance grade, and can be widely used in 70 °C cable material (IEC standard of International Electrotechnical Commission) and other PVC soft products. In addition to a large number of cable materials, PVC plasticizer, DOTP can also be used in the production of artificial leather film. In addition, the solubility is excellent, can also be used in acrylonitrile derivatives, polyvinyl butyraldehyde, nitrile rubber, cellulose nitrate and other plasticizers. Can also be used for synthetic rubber plasticizer, coating additive, precision instrument lubricant, lubricant additive, can also be used as paper softener.
Product Features
1.DOTP has good electric resistance and thermal performance. It can replace DOP in PVC plastic electrical wire sheath and can also be used for the production of artificial leather film. In addition, with excellent compatibility, it can also be used for the plasticization of acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, cellulose nitrate, etc. And plays a role in improving the hardness and deformation of products, in NBR, neoprene rubber, EPDM can be used as softener products. It is especially used in cable material with good plasticizing effect and low volatility. It is widely used in various products requiring heat resistance and high insulation. It is an ideal plasticizer for the production of cable material with temperature resistance of 70 °C and other PVC products requiring volatile resistance.
2.DOTP is used for PVC products in cars, which can solve the fog problem of glass Windows. DOTP is also used for high-quality lubricants or lubricating additives for paints, coatings and precision instruments of high quality furniture and interior decoration, nitro varnish additives, paper softeners, polyester amide bidirectional stretch film, film plastic crafts, plasma storage bags, etc.
3.Because the linear molecular structure of DOTP is similar to DOS and DOA, its cold resistance is also better.
4.The volume resistivity of DOTP is 10-20 times higher than that of DOP, and it has excellent migration resistance.
5.Because DOTP does not contain phthalates, it is not included in the 16 kinds of phthalate-containing plasticizers that are restricted in the European Union and other countries. Therefore, it is an excellent environmentally friendly plasticizer.
