ⅰ chemical formula and molecular weight
●chemical formula:c26h50o4
●molecular weight:426.68
●cas no.:122-62-3
ⅱ properties and uses
●colourless,transparent oily liquid,b.p.377℃,viscosity 25 c.p.(25℃),refractive index 1.449~1.451(25℃).
●a superior cold-resisting plasticizer,it has good plasticizing effect and better heat endurance,light-resisting and electrical properties. it is chiefly used in processing polyvinl chloride and its copolymer,cellulosic resins and synthetic rubbers,etc..
●it is usually mixed with phthalic esters in use to minimize its migration rate.
