Dioctyl terephthalate

Properties: this product is almost colorless, low viscosity liquid.Viscosity of 63 mpa. S (25 ℃), 5 mpa. S (100 ℃), 410 mpa. S (0 ℃).Freezing point - 48 ℃.Boiling point 383 ℃ (0.1 MPa), s (0 ℃).The ignition temperature of 399 ℃.The refractive index of 1.4887.The water solubility of 0.4% (20 ℃), the hydrolysis rate of 0.04% (96 hboiling water) .

 

Volatilization loss of 12% (weight) (177 ℃ heating after 24 h).Quality standard: the appearance of the transparent oily liquid, without suspended matter;Ester in % > 99.0;Density (20 ℃), 0.981 to 0.986 g/cm3;Acidity (in phthalate) < 0.015;Flash point > 210 ℃;Chroma (platinum - cobalt) < 50;Heating loss < 0.1%.

 

Properties: this product after the "SGS" test does not contain phthalates (16 p), is a kind of environmental protection, can replace a new type of plasticizer DOP.DOTP on the physical properties and mechanical properties are better than DOP.This product has the outstanding electrical properties, heat resistance, low temperature resistance of volatile, low glass transition temperature, low volatile, such as performance, is the production of fine cable material ideal plasticizer.

 

 

Purpose: the dioctyl terephthalate (DOTP) formula: C24H38O4 is one of the types of polyvinyl chloride (PVC) plastic with excellent performance of the main plasticizer.It with the current commonly used phthalates dioctyl ester (DOP), compared with heat, cold and difficult to volatilize, extraction resistance, softness and electric insulation performance is good wait for an advantage, in the products show excellent durability, low soap water and tender and soft.Because of its low volatile, use DOTP can completely meet the requirements of wire and cable heat resistance level, which can be widely applied in resistance to 70 ℃ cable material (the international electrotechnical commission IEC standards) and other various kinds of PVC soft products.

 

DOTP in addition to a large number of used in cable material, PVC plasticizer, can also be used for artificial leather membrane production.In addition, it has excellent intermiscibility, also can be used in acrylonitrile derivatives, polyvinyl butyral plasticizer, nitrile rubber, cellulose nitrate, etc.Can also be used for synthetic rubber plasticizer, paint additives, precision instrument lubricants, lubricant additives, as paper softener
