Dioctyl (O-) Phthalate

Brief Introduction of Performance and Uses of D O P Dioctyl (o-) phthalate, for short,DOP. DOP is an important and general primary plasticizer, chiefly used in the processing of PVC resin and high polymers such as chemical resin, acetic acid resin, ABS resin, rubber and also in the production of lacquer, dyestuff and dispersant,etc. DOP of general grade is widely used in the industry of plastic, rubber, oilpaint and emulsifying agent. PVC plasticized by it can be used in the manufacture of artificial leather, agricultural film, packaging material and cables,etc. Apart from having all the properties of general grade DOP, electrical grade DOP also has excellent electrical insulation and is chiefly used in the production of wires and cables. DOP of food grade is mostly used in the production of packaging material. DOP of pharmaceutical grade is mainly used in the manufacture of medical and sanitary products, such as discardable medical apparatus and instruments and medical packaging materials,etc. Quality Standards Item Standard general grade electrical grade food grade pharmaceutical grade appearance transparent liquid, no suspended substance odor no odor or slight odor no odor purity，% 99.5 99.5 99.5 99.5 Density (20 ),g/cm3 0.983-0.985 acidity,mgKOH/g 0.07 0.05 0.05 0.02 moisture content，% 0.1 chroma, (platinum-cobalt) 40 40 20 20 refractive index (20 ) 1.486-1.487 Viscosity (20 ),mPa.s 77-82 volume resistivity,?0 9 .m ----- 1.5 ----- ------ UV absorption value(220-230nm) --------------------- 0.2
