Phthalic Acid Esters
Ⅰ Chemical formula and molecular weight
●Chemical formula:C12H14O4
●Molecular weight:222.24
●CAS No.:84-66-2
Ⅱ Properties and uses
●Colourless,transparent oily liquid,slight aromatic odour,viscosity 13 c.p.（20℃）,refractive index 1.499～1.502（20℃）.
●Good compatibility with most of ethylenic and cellulosic resins. Plasticizer for cellulosic resins granting a good softening and long-lasting property at low temperature. If combined with DMP together,it may increase the water-durability and elasticity of the product.
