Adipic Acid Esters
Ⅰ Chemical formula and molecular weight
●Chemical formula:C22H42O4
●Molecular weight:370.57
●CAS No.:103-23-1
Ⅱ Properties and uses
●Colourless,transparent oily liquid,b.p.215℃（3mmHg）,viscosity 12～
15 c.p.（25℃）,refractive index 1.447（25℃）.
●A typical cold resisting plasticizer for vinyl chloride polymer and its copolymer,polystyrene,cellulosic resins and synthetic rubbers. It imparts a high plasticizing efficiency,less colour change during light and heat attack,good softening property at low temperature.
●Usually applied in cold-resisting agricultural film,artificial leather,wrapping layer for electric wires,and water tubes for outdoor use.
