Sebacic Acid Esters
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.
